FIELD OF THE INVENTION

This application is related to the field of footwear and, specificallywith regard to systems and methods for controlling a degree of flexwithin the footwear.

BACKGROUND

There is a need for varying and adjusting the flexibility and stiffnessof associated devices, apparatus and equipment to customize to a user'sunique needs, and to the requirements of a particular task or desiredoutcome.

For example, in recent years, as it relates to the category of sportsand fitness equipment, manufacturers and marketers have increasinglyturned to different kinds of methods to enhance the customization andperformance of sporting and fitness equipment. In some cases, entirelines of sporting equipment have been developed whose stiffness orflexibility characteristics are different from each other and aredesigned to be matched to the user's unique needs. Such differences,however, may be enough to give the individual equipment user an edgeover the competition in that the equipment can be more personallycustomized, matched to a desired goal, and, therefore, enhanceperformance.

Until now, the user may choose a particular piece of sporting or fitnessequipment having a desired stiffness or flexibility characteristic and,during play, switch to a different piece of sporting equipment that isslightly more flexible or stiffer to suit changing playing conditions orto help compensate for weariness or fatigue or some other anomaly thatprevents optimum performance. Such switching, of course, is subject tothe availability of different pieces of sporting or fitness equipmentfrom which to choose, at the precise moment the change or adjustment isneeded. In many cases, the availability is limited due to cost and overall impracticability.

Additionally, subtle but important changes in the stiffness orflexibility characteristics of sporting or fitness equipment may not beavailable between different pieces of sporting equipment, because thecharacteristics may be set by the manufacturer from the choice ofmaterials, design, etc., and to change the characteristics would beimpossible, as such customization isn't offered to the user. Further,the user must have the different pieces of sporting equipment nearbyduring play or they are essentially in practice unavailable to the user.

Thus, it can be seen how the lack of adjustability in stiffness andflexibility may adversely affect optimum performance of a device,apparatus, and equipment.

Turning to additional types of devices, apparatus and equipment, it canbe seen how the lack of a practical means of adjustability in stiffnessand flexibility may adversely affect performance.

Medical Devices, Apparatus, and Equipment

Medical devices, apparatus and equipment, such as braces that are usedfor supporting injured limbs, require the flexibility of the device tobe adjusted based on the degree of the injury, type of surgery, and theprogress of the healing of the injured party. Further, there is a needfor on-going protection even after recovery. Yet the degree ofadjustability of braces is limited, and, in most cases, fixed.Adjustability of the flexibility of the brace the brace to the specificneeds and requirements of the user, may enhance recovery and protectionfrom further injury.

Fitness Devices, Apparatus, and Equipment

Fitness equipment, apparatus and devices require the creation ofdifferent amounts of resistance to perform the exercise. For example,with free-weight training the user must change the weight levels toprogressively increase the resistance that the user experiences. Thisoften involves the continued and time consuming adjustment of equipmentthrough an exercise cycle and makes changes impractical at best, and atthe least a hassle.

Numerous heavy metal plates, large oily machines, weights, rubber bands,and singular resistance rods are the many known forms of fitnesstraining. When the user changes resistance/weight or machine during anexercise set, it is time consuming and interrupts the user'sconditioning.

Running Shoes, Training Shoes, Basketball Shoes

The transmission of the shoe wearer's strength (power) from their legsinto the ground is directly affected by the sole stiffness of the shoe.Runners may gain more leverage and, thus, more speed by using a stiffersole. Basketball players may also affect the height of their jumpsthrough the leverage transmitted by the sole of their shoes. If the soleis too stiff, however, the toe-heel flex of the foot is hindered. Thus,athletic shoes are tailored, by the manufacturer, to the particularsport to which the shoe is to be used. In some case, it may be possiblefor the user have the ability to tailor the sole stiffness to his/herindividual weight, strength, height, running style, and groundconditions. However, this process is performed by the manufacturer andis beyond the ability of the average user.

In footwear, various methods of materials and geometry have attempted toimprove absorption of energy when the user's feet strike the pavement,ground or sports surface, and/or then release a greater percentage ofthis energy through the gait cycle. To date, static materials andvarious geometries have been common solutions. Yet none are dynamic oradjustable by the user in real time. Spring designs in shoe solesattempt to in part absorb energy and release energy but they havesignificant limitations and cannot be practically adjusted nor can theybe dynamically adjusted in real time to current conditions.

Additionally, there is also no known way to control or adjust variouszones of the sole to produce extra traction and/or grip during pronationof supination, or to adjust the flex of a particular sole zone tocustomize for greater comfort and support.

Golf

Golf clubs may be formed of graphite, wood, titanium, glass fiber orvarious types of composites or metal alloys. Each material varies tosome degree with respect to stiffness and flexibility. However, golfersgenerally carry onto the golf course only a predetermined number of golfclubs. Varying the stiffness or flexibility of the golf club is notpossible, unless the golfer brings another set of clubs. Nevertheless,it is impractical to carry a large number of golf clubs onto the course,wherein each club having a slight nuance of difference in flexibilityand stiffness than another. Golf players prefer taking onto the course aset of clubs that are suited to the player's specific swing type,strength and ability.

Hockey

Hockey (hockey includes, but is not limited to, ice hockey, streethockey, roller hockey, held hockey and floor hockey) players may requirethat the flexure of the hockey stick be changed to better assist in thewrist shot or slap shot needed at that particular junction of a game orwhich the player was better at making.

Younger players may require more flex in the hockey stick due to lack ofstrength; such flex may mean the difference between the younger playerbeing able to lift the puck or not when making a shot since a stifferflex in the stick may not allow the player to achieve such lift. Inaddition, as the younger players ages and increases in strength, theplayer may desire a stiffer hockey stick, which in accordance withconventional means the hockey player would need to purchase additionalhockey stick shafts with the desired stiffness and flexibilitycharacteristics. Indeed, to cover a full range of nuances of differingstiffness and flexibility characteristics, hockey players would haveavailable many different types of hockey sticks. Even so, the hockeyplayer may merely want to make a slight adjustment to the stiffness orflexibility of a hockey stick to improve the nuances of the play; whichis not possible with conventional technology

Tennis

Tennis players also may want some stiffness and/or adjustability intheir tennis rackets and to resist unwanted torsional effects caused bythe ball striking the strings during play. The torsional effects may bemore pronounced in the case where the ball strikes near the rim of theracket rather than the center of the strings.

Lacrosse

Lacrosse players use their lacrosse sticks to scoop up a lacrosse balland pass the ball to other players or toward the goal. The stiffness orflexibility of the lacrosse stick may affect performance during thegame.

Other Racket Sports

Other types of racket sports also suffer from the drawback of beingunable to vary the stiffness and/or flexibility of the racket during thecourse of play to suit the needs of the player at that time, whetherthose needs arise from weariness, desired held positions, or trainingfor improvement. Such racket sports include racquetball, paddleball,squash, badminton, and court tennis.

For conventional rackets, the stiffness and flexibility is set by themanufacturer and invariable. If the player tires of such characteristicsbeing fixed or otherwise wants to vary the stiffness and flexibility,the only practical recourse is to switch to a different racket whosestiffness and flexibility characteristics better suit the needs of theplayer at that time.

Skiing, Snowboarding, Snow Skating, Ski-Boarding

Skis are made from a multitude of different types of materials anddimensions, the strength and flexibility of each type differing to acertain extent. Skis include those for downhill, ice skiing,cross-country skiing and water-skiing. For soft snow conditions, therider may want to have more flexibility so as to allow the board tofloat. For icier conditions, the rider may want to stiffen the highbackto provide greater leverage and power, which results in greater edgecontrol.

Bicycle Shoes

Bicycle specific shoes are rigid and may or may not be attached tobicycle pedals usually through a binding or clip mechanism thatprohibits the shoe from slipping of the pedal. The shoe is positioned onthe pedal so the ball of the foot is directly over the pedal. Therider's foot flexes as the pedal moves. However, the bicycle shoe isdesigned for pedaling and walking in these shoes is uncomfortable.

Fishing Rods

Fishing rods are flexed for casting out a line. The whip effect from thecasting is affected by the stiffness or flexibility of the rod.Depending upon the fishing conditions and the individual tastes of theuser, the user may prefer the rod to be either more flexible or stifferto optimize the whip effect of the cast and to deal with wind, current,types of fish, and the like. Thus, the user must select the type offlexibility or stiffness when purchasing the fishing rod.

Fins

Diving and swimming fins provide different degrees of stiffness that arefixed, and unchangeable. However, the need to have more flex or lessflex and, thus, control fin bend is dependent on the changingconditions. Optimum performance that matches the conditions may bepossible with dynamically adjustable fin spine(s). It would also beadvantages in that the swimmer/diver would not be unnecessarily fatiguedif they had proper matching flex to the conditions.

Sailboating and Sailboarding

Masts of sailboats and sailboards support sails. In many cases the usersmust adjust the amount of sail that is hanging from the mast accordingto the weather conditions to prevent damaging the mast caused by stresson the mast.

Canoeing, Rowboating and Kayaking

Paddles for canoes, row boats, and kayaks are subjected to forces asthey are stroked through water. The flexibility or stiffness of thepaddles, while different depending upon its design and materials, isfixed by the manufacturer. Thus, a rower who desired to change suchcharacteristics would need to switch to a different type of paddle.Carrying a multitude of different types of paddles for use with a canoe,row boat or kayak, however, is generally impractical for the typicalrower from the standpoint of cost, bulk and storage.

Lawn Rake

There are times when the flex of a rake's tines are either too flexibleor too stiff for the task at hand, be it for raking gardens, light leaf,matted thatch, wet grass, debris. Often the user has to purchase asecond rake to accommodate these additional needs.

In addition to athletes desiring to customize their equipment anddisclosed previously, athletes have increased physical performancedemands for each sport specialty they play, and therefore requiredifferent shoe types to enhance their athletic performance, style andtechnique.

Athletes and the general population all, to some degree, have pronation,supination and heel cushion issues when walking, running and/or playing.

Shoe soles are typically generic, static and are not adjustable onceassembled or molded. This fixed or static quality offers the wearer noafter-market method to adjust the performance of a shoe or shoe sole.

Hence, there is a need in the footwear industry of a platform systemintegrated into the sole of footwear that provides the user with theability to customize or adapt their footwear in order to provide acomfortable fit during different activities, to improve performance, andspecifically for the ability of the user to customize and control thedegree of energy absorption, and release of energy commensurate with theactivity demands.

SUMMARY OF THE INVENTION

The invention relates to a variable resistance beam or rod that maydynamically control the stiffness and flexibility of devices, apparatus,and equipment. The resilient rods, beams or shafts of solid, semi-solidor hollow construction produce resistance and variable resistances whenorientated in a direction of x, y, z plane or combination of planes in360 degrees of rotation or bending movement.

The variable resistance rod (VRB) technology may be incorporated intodifferent equipment (sports & fitness, lawn, medical, etc.) that requiredifferent degrees and direction of stiffness and flexibility, whereinthe different degrees of stiffness and flexibility may be controlled inthe field in real time by means of a selector, a worm gear, or othermechanical methods to affect a rotated orientation of the variableresistance rods, or by simple hand placement in relation to the fulcrumindicated by an indicia of color, number, symbol or other means.

One aspect of the invention resides in a resilient or resistance rodacting to create variable resistance that incorporates a selectable oradjustable flex resistance by means of hand position and placement.

One aspect of the invention resides in a resilient rod, beam or shaft,including at least one spine, extending substantially the length of therod, beam or shaft, that provides for variable degrees of flexibility ofthe rod, shaft or beam depending upon the orientation of the spine withregard to a direction of flex

One aspect of the invention resides in equipment that adjusts to providevariations in stiffness and flexibility. The equipment may have a rod,beam or shaft with an elongated cavity or rod, an elongated flexureresistance spine, one, two or more locking elements that secure the rod,shaft or beam against rotation at spaced apart locations within thecavity. The rod, shaft or beam is stiffer and less flexible in onedirection than in another.

Another aspect of the invention resides in sports equipment thatprovides variations in stiffness and flexibility. The sports equipmentmay have an elongated cavity, and a means imparting stiffness andflexibility variations within the cavity so the sports equipment becomesstiffer, and less flexible, in one direction than in another, and one ormore locking elements that secure the means against rotation in spacedapart locations within the cavity.

A further aspect of the invention resides in a method of varyingstiffness and flexibility, comprising providing equipment (e.g., sports& fitness, medical, footwear & sneakers) having an elongated cavity;imparting stiffness and flexibility variations within the cavity so thatthe equipment becomes stiffer and less flexible, in one direction thanin a different direction; and securing against rotation at least onelocation within the cavity while imparting stiffness and flexibilityvariations.

An additional aspect of the invention resides in a resilient shaft orbeam acting alone to create variable resistance that incorporates aselectable or adjustable flex resistance by means of varying handposition and placement on the resilient rod in relationship to thefulcrum of the bended rod.

An advantage of the present invention is the ability to provide constantand consistent flex adjustment. This advantage arises from theadjustment being locked in at the ends of the shaft and, depending uponthe application, at one or more additional locations through the lengthof the shaft.

A resilient rod acting alone is also embodied to create resistance thatincorporates adjustable flex or resistance by means of hand positionand/or specific rotation for means of exercise employing progressivedynamic resistance, which relates to the advantages in exercise ofvarying degree weight and resistance through a particular cycle.

Footwear, as is known, generally provides a user with a stable platformupon which the user may walk, run, jog, exercise, etc. The presentinvention embodies a platform integrated into the sole of footwear whoserigidity provides leverage to the variable resistance beams (VRB) forselectable bio-mechanical advantage for the user.

In accordance with the principles of the invention, an adjustable andcustomizing support zones of a shoe sole is provided by the embedding orinsert molding into the matrix of the sole, a new and novel footwearmodule or adjustable platform system to augment athletic and everydayperformance.

The footwear platform is a module based design to be embedded intospecific areas of the shoe sole, to maximize beneficial VRB mechanics,flexural leverage and energy return, to augment natural movement andcorrect misalignments of the foot across multiple shoe sole type.

The composite structure of a shoe sole combined with an insert moldedmodule allows the shoe sole to flex in proportion and concert with theVRB flex seeting and/or per zone of the sole.

The incorporation of the VRB into the shoe sole provides a greaterflexibility rand or lower resistance to sole flex when the VRB is in itslow setting and greater resistance of sole flex and greater support, perzone when in its high setting.

In accordance with the principles of the invention, VRBs act asadjustable resistance cantilevers to provide a selectable range ofdynamic and reactive suspension to the foot, in one or multiple zones.

In accordance with the principles of the invention one or more VRBs inan integrated platform system are applied to footwear structures tosupport the foot. The invention generally delineates one or more VRBsper zone to biomechanically affect, support, correct and or enhance anyimbalance of the lower extremity or foot, or to proactively adjuststiffness in real time to gain greater performance benefits.

VRBs act as adjustable resistance cantilevers to provide a selectablerange of dynamic and reactive suspension to the foot.

In accordance with the principles of the invention, Multiple VRBs orzones can be employed to correct and support the bio-mechanical needs ofthe user. Typically up to 4 or more VRBs or zones are employed topositively biomechanically correct imbalances or enhance athleticperformance of the front right/left and rear right/left sections of thefoot.

The invention also embodies flexible materials that form geometries andsole structures that ergonomically conform, deform, and/or change shapeto the mechanical setting of the VRB resistance range settings.

Additionally, as one example of flexible mid arch material withadaptable geometry connected to a VRB to impart selective and correctivereal-time reactive bio-mechanical support, a VRB would impart increasingor decreasing vertical height to meet the user's ergonomic arch shapeand bio-mechanical arch support requirements.

In accordance with the principles of the invention, the integratedsuspension system may be connected to a corresponding VRB to impartselective, reactive and corrective real-time, bio-mechanical support.

In accordance with the principles of the invention, the uniquebiomechanics feature of selectable dynamic suspension coupled to producea conformal adapting orthotic shell geometry to support the foot indirect proportion to foot loading is called self or auto leveling.

In accordance with the principles of the invention, an optionalsynthetic plantar fascia or rubber connector tendon may be utilized tojoin two modules together, while embedded in the shoe, to capture andrelease additional stored energy from sole flexure.

In accordance with the principles of the invention, this synthetic (orrubber or elastomeric material) connector may provide additional energyreturn from being stretched and released, typically during the last ⅔ to¾ toe off period of the gait cycle.

In accordance with the principles of the invention, a modularelastometic unibody or polymeric platform anchors each individual VRBvia a threaded socket, that simultaneously acts as a VRB placementholder and a VRB resistance selector.

Each anchor module is typically comprised of an elastomeric materialwith one or two VRBs, threaded into a corresponding VRB placement holderi.e., threaded receiver).

In accordance with the principle of the invention, a plurality of VRBs(e.g., 4 VRBs, for quadrant zones) may be employed for each sole withtypically one VRB for each zone to provide selectable support range tocustomize the shoe sole.

In accordance with the principles of the invention, the VRB incorporatesa threaded or helix section that is typically located at a mid or an endjoint location along the a long (longitudinal) axis of the VRB. Thehelix or screw thread provides continuous and incremental VRB adjustmentcapability in any of zero (0) to ninety (90) degrees of rotation. Threadpitch determines the travel distance the VRB forward or rearward (linearadvance) while rotating from a minimum to a maximum resistive position.

In accordance with the principles of the invention, a modularelastomeric platform incorporates a threaded pocket or socket thatanchors a corresponding VRB. The threaded socket operates simultaneouslyas a VRB selector and a VRB receiver. Each module anchor is moldengineered to a specific inside diameter with tight mating tolerance toeach outside diameter VRB barrel with threaded helix. The combinedinside diameter and outside diameter mating fit combined with themodule's material coefficient of friction (i.e., material durometer)grips the vRB and holds the VRB in any incremental, fixed rotated orselected position.

Each module typically houses two vrb selectors/receivers aligned ineither a perpendicular orientation and or in an obtuse (greater than 90°but less than 180°) spread angle or symmetrically flared configuration.

In accordance with the principles of the invention the module'sselectors lay in a same flat or horizontal plane but may also beinclined to increase advantageous VRB flexural mechanics.

In accordance with the principles of the invention, the flexibleelastomeric VRB anchor platform provides for independent torsion (sideto side twisting or flexing) for each individual VRB zone.

The VRB modules can either be independently embedded into the shoe sole(unconnected) and/or connected by an elastomeric tendon acting as asecond plantar fascia tendon.

In accordance with the principles of the invention, the optional use ofa synthetic plantar fascia or rubber elastomeric connector tendonbetween the two modules embedded in the shoe sole to capture and releasestored energy.

Additionally, an enhanced performance range of selectable support may beachieved by wrapping the elliptical or rectangular VRB cross sectionwith high tenacity tensile thread (braided or not) made of cotton,nylon, polyester, kevlar, spectra, dyneema, nanowire et al.

The VRB may be molded from polymeric materials, GRP glass reinforcedpolymers or machined from high tensile spring metal and/or martensiticsteels, all incorporating a threaded helix to rotate (and fasten) into amatched module receiver/selector threads.

Additionally, patterned guide grooves may be molded or machined into theVRB shank or flexing segment of the VRB for thread wrapping.

The guide grooves ensure a consistent structural wrapping pattern forthe high tensile thread, to increase the VRB's mechanical (flexural)strength envelop achieved by forming a composite beam, formed from twocomplimentary materials.

VRB mechanical flex range can be increased or decreased dependent uponthe number of thread windings or wraps along the VRB shank and or thetensile strength of the winding thread.

The net mechanical effect of using a VRB polymer with a high Young'smodulus or spring strength (e.g., Nylon) wrapped by a high tensilethread, creates a modulated and super strong variable resistantcomposite beam, with a wider mechanical Minimum to Maximum selectablesupport range.

The composite mechanical flexural beam effect is analogous to slow andfast twitch muscle fibers and is self-moderating and provides for acontrolled return rate.

In accordance with the principles of the invention, this moderation orrate level of reaction to being mechanically flexed can be engineered tomatch the flex cadence of the gait of the foot.

The VRB complimentary materials' compression and tension return ratecharacteristics may be engineered to return to their natural or neutralstate at a controlled rate matched to the cyclic human gait.

In accordance with the principles of the invention, It is possible tomatch the beam's flexural characteristics with the natural cadence ofthe human gait, by controlling the Young's modulus of a VRB's corepolymer matched with a tensile strength of high tenacity wrappingthread, e.g., flexural cadence of the foot gait cycle matched to theflex recovery time of the two composite VRB (polymeric) materials.

In accordance with the principles of the invention, additionalcapability may be achieved by applying sensors to one or up to four ormore flexing VRBs, to provide the ability to measure VRB beamperformance and predictably that of the wearer or athlete. This impartsuseful biomechanics data to monitor, quantify and record the physicalexertion and warn of potential injury factors from overuse. Data iseither collected onboard an embedded PCB (printed circuit board) ortransmitted wirelessly to a smart device.

The foot supporting plate described herein incorporates a superior,elastomeric based module to anchor the vrbs. The modular system providesfor multiple placements within any existing shoe sole, brand or type.

DETAILED DESCRIPTION OF THE INVENTION

The object of the present invention is to adjust the flexibility andthereby the resistance of a rod by hand positioning in relationship tothe fulcrum of rod; or by bending a rod and spine within the shaft; orby bending a single solid rod; or both the bending of an outer beam andan inner beam in another example. This affects the longitudinal flex andthe kick or hinge point of flexure where maximum flexure bending forcesarise, depending on the hand position or anchor point in relationship tothe fulcrum.

A shaft includes any tube-like structure by itself, attached to theoutside of another surface or incorporated within a structure. Examplesof a tube-like shaft by itself include hockey sticks, golf clubs,lacrosse sticks, pole vaulting poles, fishing rods, sailboard/sailboardmasts, canoe/kayak paddles or oars, baseball bats, archery bows, tennisracquets and exercise machine tensioning rods. Examples of products towhich a tube-like shaft might be attached externally include skis,snowboard bindings and bicycle frames.

A beam or rod includes any solid, semi-solid or hollow elongatedstructure or rod, wherein the rigidity of the beam or rod is dependentat least upon the thickness of the material constructing the beam andthe type of material. In the case of hollow beams or rods, the rigidityof the beam is also dependent upon the thickness of the wall forming thebeam or rods and the material constructing the wall.

A spine includes any longitudinal structure whose flexure is differentin one plane than another, in any increment of 0 to 90 degrees. This canbe achieved using many materials. Examples of design shapes that havethis property include, but are not limited to, I-beams, ovals, stars,triangles, rectangles, stacked circles, ellipses, etc. The spine may besolid or hollow in construction and utilize combinations of differentmaterials and material thicknesses to achieve the preferred flexibilityprofile and characteristics.

FIG. 1A (a)-(c) illustrates an exemplary embodiment of a type I VRB(variable resistance beam) 100 having a circular cross-sectional area105. Also illustrated is a series of beams 100 having cross-sectionalarea 105 that demonstrate the various fulcrum changes through changinghand placement. Each new hand position provides a different resistancesuch that the resistance increases as a fulcrum length, from a fixed orattached point, decreases, and in the inverse, how resistance decreasesas the fulcrum length increases.

FIG. 1B (a)-(c) illustrates an exemplary embodiment of a type II VRB 100having a circular cross-sectional area 110 including at least one outergeometric spline 112. Also illustrated is a series of beams 110 withouter geometric spines, demonstrating the various fulcrum changesthrough hand placement. Each new hand position provides a differentresistance. Further illustrated is how the resistance increases asfulcrum length decreases, with respect to a fixed attachment point, andhow resistance decreases as the fulcrum length increases.

Also illustrated is a change in the resistance of the VRB 100 having acircular cross-sectional area 110 as the orientation of the outersplines is rotated with respect to a bending force. In this illustratedexample, the resistance to the bending force is maximum when theorientation of the outer splines is parallel to the bending force andminimum when the orientation of the outer splines is perpendicular tothe bending force.

FIG. 1C(a)-(c) illustrates an exemplary embodiment of a type III VRB 100having a cross-sectional area 115 including a combination of an outershaft having external splines and an inner shaft having internalsplines. That is, type III VRB 100 represents a hollow 2-cam crosssection. Also illustrated is a series of beams with internal rods orshaft, that have geometric spines, demonstrating the various fulcrumchanges through hand placement. Each new hand position provides adifferent resistance. Further illustrated is how the resistanceincreases as fulcrum length decreases with respect to a fixed attachmentpoint, and how resistance decreases as the fulcrum length increases.With respect to the fixed attachment point. Also illustrated is a changein the resistance of the type III VRB 100 as the orientation of theinner splines is rotated with respect to a bending force. In thisillustrated example, the resistance to the bending force is maximum whenthe orientation of the inner splines is parallel to the bending forceand minimum when the orientation of the inner splines is perpendicularto the bending force.

FIG. 1D (a)-(c) illustrates an exemplary embodiment of a type IV VRB 100wherein at least one elliptical section is removed from the crosssection 120. In this illustrative example, the reference Side Brepresents an area within the type IV VRB 100 that is removed from theVRB. FIG. 1D further illustrates side views of type IV VRB 100illustrating the removal of area referred to as Side B from the type IVVRB 100. Also illustrated is a type IV VRB 100, that has ellipticalscallop cuts along the inner rod or shaft, demonstrating the variousfulcrum changes through hand placement. Each new hand position providesa different resistance, wherein the resistance increases as a fulcrumlength decreases, and decreases as the fulcrum length increases.

FIG. 1E(a)-(c) illustrates an exemplary embodiment of a type V VRB 100having a cross-sectional area 125 comprising a major axis longer thanminor axis. That is type V VRB 100 illustrates ellipsoidal beams (hollowor solid) with a major axis longer than a minor axis. Also shown is aseries of type V VRB 100 demonstrating the various fulcrum changesthrough hand placement. Each new hand position provides a differentresistance. Further illustrated is how the resistance increases asfulcrum length decreases, how resistance decreases as the fulcrum lengthincreases.

FIG. 1F (a)-(c) illustrates an exemplary embodiment of a type VI VRB 100having a cross-sectional area 130 comprising a spine reinforced tubularor conical rod. Also illustrated is a series of type VI VRBs 100demonstrating the various fulcrum changes through hand placement. Eachnew hand position provides a different resistance. Further illustratedis how the resistance increases as fulcrum length decreases, and in theinverse, how resistance decreases as the fulcrum length increases.

Also illustrated is a change in the resistance of the type VI VRBs 100as the orientation of the inner splines is rotated with respect to abending force. In this illustrated example, the resistance to thebending force is maximum when the orientation of the inner splines isparallel to the bending force and minimum when the orientation of theinner splines is perpendicular to the bending force.

FIG. 1F further illustrates that the type VI VRBs 100 may also be of acylindrical or a conical shape.

FIG. 1G (a)-(d) illustrates an exemplary embodiment of a type VII VRB100 beams having a rectangular cross-section 135. As shown therectangular cross-section may be sized in different ratios (e.g., 4:3,2:1) to provide different resistance to bending force. For example, in acase of a 2:1 ratio cross sectional area, the resistance to a bendingforce applied to the greater side is twice as great at that of thelesser side. The rectangular type VII VRB 100 may be solid or hollow asdesired.

Additionally, the resistance rods (VRBs) may include a plurality ofgraduated indicia that indicate bending resistance by measurement of afulcrum distance from an anchored position to a hand position[s], asshown.

Thus, in one aspect of the invention, rods with symmetrical crosssections vary their bending resistance by shortening and lengthening thearc length, from fulcrum to anchor point by hand position per indicia.

In another aspect of the invention, rods with asymmetrical crosssections may increase or decrease their bending resistance by rotationof the elongated orientation with respect to a bending force, whilemaintaining the same hand position or fulcrum length.

FIG. 2(a)-(f) illustrates the various fulcrum changes through handplacement. Each new hand position provides different resistances. VRB205 illustrates the variables resistances from a cylindrical beam, rodor bar. VRB 210 illustrates the variable resistances from a type II VRB100 beam, with added geometric spines, indicating, in this instance, thetwo-three times increase in pull resistance per identical hand positionsalong X/Y planes.

Table 1 illustrates exemplary resistance levels for differentconfigurations of the VRBs shown in FIG. 1 and FIG. 4 for a knownmaterial. In this case, resistance levels of VRB of 54 inch length,including 6 grip sections, each grip section being 3 inches for 9/16, ⅝and ¾ inch nominal VRBs are determined.

As shown in Table 1, the resistance level increases with the addition ofa geometric spine in this example. In addition, by shortening orlengthening the arc length/fulcrum during bending of the beam theresistance may be decreased or increased.

TABLE 1 9/16 inch thick bar ⅝ inch thick bar ¾ inch thick bar DistanceWith Spine With Spine from Min/Max Min/Max fulcrum No Spine Res No SpineRes No Spine 51 7  8/15 10 11/21 22 48 8  8/16 11 12/23 24 45 9  9/18 1314/25 26 42 10 10/20 14 15/28 29 30 11 11/22 16 17/32 33 36 12 13/26 1820/37 38

Also shown, the resistance level increases as the material thicknessincreases. In addition, the resistance level increases from a minimum toa maximum value as the orientation of the spine with respect to thedirection of the flex increases.

Hence, the resistance level that may be achieved at each hand leveldepends on the thickness of the VRB and the material composing the VRB.Although not shown it would be recognized that the resistance level mayfurther be based on whether the VRB is hollow. With a hollow VRB, theresistance of the VRB depends on a thickness of the outer wall of theVRB.

FIG. 2A(a)-(f) Illustrates a comparison of a symmetric or basicallyround and or an asymmetric or elongated cross sectional VRB 100 rod heldat two positions. Increasing or decreasing resistance is generated byeach rod with a fixed or anchored hand position 215 and a moving handposition 220 into each indicia zone. This distance between fixed handposition and the moving hand position is described as the fulcrumlength.

As the fulcrum length or distance between the fixed hand position 215and the moving hand position 220 increases, the resistance decreases. Asthe distance between the anchored hand position and the moving handposition decreases, resistance increases.

FIG. 3(a)-(c) illustrates a VRB 100 with an outside diameter with markedsets of indicia that specify the range of flexural resistancesproportionate to the tensile strength of the beam material and fulcrumlength per hand position[s] for symmetric or basically round (1 set) and(2 set) asymmetric or elongated cross sections.

FIG. 3 (a)-(c) illustrates a side view 300 of an exemplary embodiment ofa VRB 100 in accordance with the principles of the invention. In thisillustrative embodiment, a symmetric VRB 100 may include a plurality ofhand positions 315, which indicate one set of resistance ranges inrelationship to the fulcrum point. An asymmetric VRB 100, it may includea plurality of hand positions 310, which indicate two sets or multiplelevels of resistance ranges in relationship to the fulcrum point androtated orientation.

FIG. 4 illustrates a view of an exemplary embodiment 400 of an equipmentincorporating a VRB 100 in accordance with the principles of theinvention. In this illustrative embodiment, a VRB 100 can be insertedinto a plurality of insertion points or rod holders 420. The exerciseequipment includes a plurality of tracks 410, a plurality of rod holders420, a bench 430 that may be positioned substantially perpendicular tothe plurality of tracks 410 or at an incline angle with respect to theplurality of tracks.

The tracks may be mechanically fixed in vertical or horizontal planes orany combination to maximize rod bend, defined as mechanical work orexercise matched to human proportion or otherwise described as theergonomic interface.

FIG. 5 illustrates a view of an exemplary embodiment of an equipment 500in accordance with the principles of the invention. In this illustrativeembodiment, a VRB 100 can be inserted into a plurality of insertionpoints. The equipment 510 includes at least one track, which can be wallor floor mounted. Each of the at least one tracks includes rod holders520. In addition, the walls 530 of the rod holder may be perpendicularor conical with respect to the track 510. Rod holders 520 may furtherinclude a stabilizing foot 540 in contact with track 510.

The anchored resistance rod (VRB) generates increased or decreasedresistance by anchoring the rod at its base and therefore the user cancontrol the degree of rod bend.

This allows the rod to be used as a dynamic resistance beam for usefulexercise. The beam resistance is dependent upon the degree of bend andhand position.

FIG. 6 illustrates a view of an exemplary equipment 600 in accordancewith the principles of the invention. In this illustrative embodiment, aVRB 100 can be inserted into selected ones of a plurality of insertionpoints 610. In this exemplary embodiment, a plurality of perpendicularrod holders or insertion points 610, similar to those described withregard to FIG. 5, may be incorporated onto a handheld transportablefolding workout platform 600.

FIG. 7 illustrates a view of an exemplary equipment 700 in accordancewith the principles of the invention. In this illustrative embodiment, aVRB 100 held in place by foam or other lightweight material 710 within ahollow shaft 720. The position and/or orientation of the VRB 100 withinthe hollow shaft 720 may determine the stiffness and/or flexibility ofthe hollow shaft. That is, in the case, a type I VRB 100 is incorporatedinto the hollow shaft 720, the length of the type I VRB 100 maydetermine the stiffness of the hollow shaft. On the other hand, if atype II VRB 100 is incorporated into the hollow shaft, then theorientation of the splines to a proposed bending force determines thestiffness and/or flexibility of the hollow shaft 720.

The resistance beam upon manual customized selected rotation impartsgreater flexibility or rigidity to the hockey stick by the user, tocustomize the equipment's response to the user's athletic ability.

Additionally, another method of imparting greater flexibility orrigidity is to raise or lower the resistance beam within the shaft tochange the fulcrum or kick point of the stick.

FIG. 8 illustrates a view of an exemplary embodiment of an equipment 800in accordance with the principles of the invention. In this illustrativeembodiment, an internal VRB 100 is held in position within a hollowshaft by a lightweight material 815, as described with regard to FIG. 7.In addition, one end of the VRB 100 is positioned on a bushing 810comprising a flexible material such that it may compress or expand aspressure is applied to the bushing 810. In one aspect of the invention,the bushing may be made of an elastomeric material such as a polymer,foam, urethane, rubber, or so the similar material that may becompressed and returned to an original state when the compressive forceis removed. At a second end, the VRB 100 is attached to a means 820 forraising or lowering the VRB within the hollow shaft. The means 820 maybe a worm gear type mechanism that raises or lowers the VRB 100, tocreate a variable shaft flex. The VRB 100 may be lowered by compressingthe bushing material 810 and raised by removing the compression pressurefrom the bushing material 810. Although the means for positioning theVRB 100 is shown as a worm gear that may be turned by an Allen key, itwould be recognized that other types of rotating means may beincorporated without altering the scope of the invention. For example,the means for adjustment to alter the position of the VRB 100 may be ascrew thread position along the outside of the hollow shaft and theturning of a cap on the top of the hollow shaft may lower or raise theVRB 100.

In the illustrated embodiment of the invention shown herein, a VRB 100rod is centrally raised or lowered within the hollow shaft to increaseor decrease flexibility or rigidity of the golf shaft, thereby shiftingthe kick point or maximum point of flexure up or down the hollow sectionof the shaft.

Thus, the player or user may select a shaft flex or rigidity range thatmatches the player's specific swing type, strength and ability.

The 360 degree symmetrical geometry provides a solution for anadjustable golf club and would be fully compliant with the existing USGA(United States Golf Association) rules of golf.

FIG. 9 illustrates an exemplary ski sports equipment configuration 900with an adjustable resistance beam VRB 100 that imparts a resistancerange along a length of the body of the ski in accordance with theprinciples of the invention.

The adjustable resistance beam VRB 100 imparts a range of performancecharacteristics into the ski to match the skier's skill and terrainrequirements.

In one application of the VRB described herein, downhill skiing requiresa very rigid ski. By adjusting the resistance beam to the highestrigidity setting, the ski will become more rigid with a faster dynamicresponse when carving turns. A more rigid ski is desirable for icyconditions due to the ability to hold its shape and maintain maximumedge contact with the snow and ice surface.

In another application, mogul skiing over bumps requires a flexible ski.By adjusting the resistance beam to its most flexible setting, the skiwill become more conformal to bumps and bend and flex over them.

Thus a terrain adaptable ski is created from a mechanically joinedadjustable resistance beam.

The means for positioning the VRB 100 may be similar to that describedwith regard to FIG. 8.

FIG. 10A illustrates a view of an exemplary embodiment of a lawnequipment 1000 in accordance with the principles of the invention. Inthis illustrative embodiment, tines are individual VRBs 100, and can besimultaneously adjusted to create equal flex in each tine.

FIG. 10B illustrates a bottom view of an exemplary embodiment of a lawnequipment 1000 in accordance with the principles of the invention. Inthis illustrative embodiment, the tines VRB 100 may be simultaneouslyrotated equally to create variable flex.

The rotated tines are locked into an incremental range of resistancepositions that are either the most flexible for raking leaves or themost rigid to raking gravel. At the end of each tine is an ellipse thatacts a hook dependent upon its rotated orientation.

FIG. 11 illustrates a view of an exemplary embodiment of an equipment1100 in accordance with the principles of the invention. In thisillustrative embodiment, internal VRBs 100 are adjusted to create avariable flex. Equipment 1100, which represents an athletic shoe,includes a rubber shoe sole 1115. The athletic shoe 1100 furtherincludes a heel fulcrum 1125 and a toe fulcrum 1130. Between the heelfulcrum 1125 and the toe fulcrum 1130 is an internal cavity 1110. Withincavity 1110 is positioned at least one VRB 100. The VRB 100 includesanti-rollover collars 1110 a, which prevent the VRB beam deflection ordistortion and are spaced along the VRB 100. The at least one VRB 100located within the internal cavity 1110 may be adjusted by an adjustmentmeans 1120 that rotates the VRB within cavity 1100. The VRB 100 isfurther locked in position. The means for positioning the VRB may besimilar to that described with regard to FIG. 8.

The transmission of the shoe wearer's strength (power) from their legsinto the ground is directly affected by the sole stiffness of the shoe.By employing an adjustable resistance beam as described herein, runnersmay gain more leverage and, thus more speed, by using a responsive shoesole customized to their specific requirements.

An adjustable pair of resistance beams within the shoe sole may beinsertable, insert molded or structurally connected to the shoe sole inlateral and/or longitudinal positions within the sole and are rotatableto a fixed and mechanically locked position to effect custom flexuralresistance range that matches the wearer's optimum performancerequirement.

Thus, the resistance beam technology described herein is designed to bea dynamic, adjustable, in-sole suspension system that can absorb theweight of the wearer and release it per each step.

In accordance with the principles of the invention, a VRB footwearsuspension support system to provide selectable suspension support maybe incorporated into the sole of footwear to provide adjustable supportin quadrant zones of the footwear is disclosed.

The VRB footwear suspension support system supports the zones of thefoot from the VRBs dynamic, reactive, selective resistance to loadingand unloading, resulting in dynamic suspension per one or more zones,e.g. mid arch et al, providing vertical lift from the VRB cantilever tomaintain physiologic support with bio-mechanic balance and comfort.

The VRB footwear suspension support system platform effectively maps thedifferential loading points with resistance or suspension levels of thefoot per zone and compensates with reactive support that can beselectively increased or decreased to match any podiatry foot conditionor performance enhancement for sports or extreme physical activity, e.g.military, where the wearer's loads are often variable.

The VRB footwear suspension support system platform acts as a type ofselectable leaf spring suspension in multiple zones, a cat's paw ormulti-zone cantilever in the shape of an ‘X’ to combine variableresistance settings and/or height geometry from VRB dynamic suspension.This reactive system vertically ‘reacts’ or lifts body weight loadsplaced upon its surface per zone, to maintain and respond toproportionate bio-mechanical foot balance loading and therefore comfortor pain relief, with athletic enhancement.

In conjunction with a dedicated mid arch zone or individual VRB archstructure integrated with the footwear cat's paw or X platform with upto four (4) VRBs to create a completely multi-zone adjustable anddynamically supportive footwear.

The reactive, dynamic and selective support levels of the footwear zoneswith VRBs are a function of the VRBs inclination angle, length andwidth, material tensile strength or fulcrum position in relation to theunderside of the foot loading, and/or extension from within shoe sole.Additionally, selectable resistance in conjunction with differentvariable footwear shell geometries provides a wider prescriptiveresistance range to match heavier bodyweights, severe in-field operatingrequirements, and/or corrective foot conditions.

In accordance with the principles of the invention, the VRB footwearsuspension support system platform and mid arch flex with the VRB so asto provide responsive dynamic and zoned suspension support withconformal geometry mapped to foot loading. The suspension platformmaximizes surface area by distributing loads over a greater area, with aresponsive and dynamic conformal surface to support the loads in realtime and proportion.

Additionally, by extending the length of one or more VRBs, the VRBsbecome extendable into one or more of the four (4) quadrant zones of theshoe to impart selectable dynamic responsive support to the bio-mechanicloads placed upon the suspension platform. A single VRB may act as adual cantilever to support two different support zones or structures,e.g. a VRB may support the foot arch and rearward heel zone by one ormore fulcrums or ‘stops’ placed along the VRB length to impartcalculated, and therefore, selectable cantilevered suspension to dualzones.

In accordance with the principles of the invention, a VRB acting as acantilever provides dynamic arch support over a selectable range tomatch a wearer's biomechanics corrective requirement with comfort. If aprescriptive setting is initially too stiff, hard or uncomfortable forthe wearer, a lower VRB setting may be used to allow the wearer‘break-in’ time for re-alignment processes of the foot structures tocorrect, thus maximizing comfort with prescriptive benefit and enhancedcustomized athletic performance.

Additionally, one or more VRBs are extendable into each of the 4quadrant zones of the shoe to impart selectable dynamic responsivesupport to reduce the ‘break-in’ period for the shoe, increasingcomfort.

The VRB selectable support range provides for a range of loads thatcontrols the supportive flexure of footwear. This in turn providesreactive geometry that will flex in proportion to the VRB setting andtherefore impart dynamic support proportional to loading.

In accordance with the principles of the invention, the zone loadingand/or mid arch loading and, therefore, the VRB loading curve[s] or thequantified in vertical lift force in pounds (Lbs) of response to weightloads placed on the VRB extending into each shoe zone and/or mid archshell structure are bell curved. The bio-mechanic effect of a cantileverabsorbing and releasing proportional loads in a Bell Curve results inmaximal comfort throughout the entire gait cycle and at each VRBresistance setting. This is an important and intended integral designengineered bio-mechanic effect of using cantilevers to dynamicallysupport body joints, e.g. foot et al., to provide a smooth bell curveresponse for maximal comfort throughout the flexural VRB range.

The mechanical resistance or support of the VRB can be design engineeredto correspond to any required loading curve, e.g. rehabilitative, postsurgical, prophylactic, extreme sports, performance enhancement and themilitary for high rucksack equipment loading in pounds (Lbs). Equally,more robust VRBs can be easily incorporated into footwear to support thearch from heavy equipment loads carried via rucksack, e.g. 100 Lbs ormore.

In accordance with the principles of the invention, responsive,proportioned and dynamic zone(s) of support create a self-levellingstructural VRB footwear suspension support system, enhancing thewearer's athletic ability or dynamically correcting imbalances. Thisprovides a real time, proportionately customizing footwear to supportthe load requirements of the foot.

The greater the load upon the foot, the greater VRB vertical suspensionor resistance to compression by immediate vertical (dynamic height)lifting support. The self-leveling platform matches the dynamic loadsplaced upon the zones of the foot/arch in proportion to load. The VRBcompression and release of load results in proportional, verticallifting support to the arch of the foot or per zone.

The arch and zones are supported by one or more VRBs that dynamicallyreact in direct proportion to the loads placed upon them. The VRBfootwear suspension support system can be ‘pre-loaded’ or positioned ata higher height geometry to allow the foot to engage and proportionallycompress and engage the VRB zones (mid arch, et al.) of support levelsto ensure a mapping of supported structure with cantilevered resistanceranges. Each individual zone is selectable with customizable suspensionrange.

In accordance with the principles of the invention, the VRB technology,disclosed, herein, dynamically supports the foot, to stabilize pronationand supination mechanics, by providing customizable, dynamic, cantileverbased suspension ranges with up to four or more cantilevered VRB zonesof selectable resistance, to further support and correct bio-mechanicalimbalances of the foot.

The unique cantilevers configuration of variable resistance beamsproduces a significant range of selectable performance resistance levelsto match a body weight or specifically foot condition.

Additionally, the footwear platform disclosed, herein, providesselectable flex that represents an integrated anti-pronation/supinationand posting mechanisms that responds to increasing medial loads bydynamic stiffening in proportioned response to body weight loading. TheVRB resistance to compression or suspension is designed to beselectively increased or decreased prescriptively to maximizetherapeutic benefit with comfort.

The cantilever system disclosed herein provides selectable incrementalresistance to pronation/supination “on demand” to meet the needs of awide range of patient foot imbalances, comfort requirements and podiatryconditions.

FIG. 13A illustrates a perspective view of an exemplary embodiment of aVRB footwear 1300 including a VRB suspension support system 1303 inaccordance with the principles of the invention.

As shown in FIG. 13A, the VRB footwear variable resistance andsuspension system 1303 includes a plurality of VRBs 1310, which areinserted through heel 1340 and extend to the platform section 1350,positioned below an insole or force plate 1305 of footwear 1300.

Further illustrated is heel section 1340. Flat surface 1345 and frontsection 1360 rest on a same plane.

As will be discussed, the VRB 1310 comprises a generally elongatedcylindrical beam or bar that includes a major axis greater than a minoraxis. The orientation of the VRB 1310 with respect to platform 1350determines a degree of flexibility (or rigidity) that supports a footload impacting or applied to the platform 1350. The VRB 1310 may beoriented at different degrees of orientation with regard to its majoraxis in order to adjust the degree of flexibility (or rigidity) ofplatform section 1350. The degree of rotated orientation imparts aselectable resistance range per increment of rotation. For example,using an elliptical VRB, as is described with regard to FIG. 22D, in a90° vertical or long axis position, the VRB 1310 is most rigid, while inthe 0° horizontal (flat) position, VRB 1310 is most flexible. VRB 1310operates as a cantilever to dynamically support and suspend the mid archsection 1350 with selectable resistance. In one aspect of the inventionfor selecting resistance, tensile strength of the material comprisingVRB 1310 may be selected to affect flex performance, e.g., 1,000, 5,000,10,000 or higher PSI Polymer tensile modulus.

As shown, VRB 1310 extends at an angle from heel section 1340 toplatform section 1350 to form a cantilever upon which platform 1350rests. As a load is applied to the platform section 1350, the platformsection 1350 engages and depresses VRB 1310. Based on the orientation ofVRB 1310 with respect to platform section 1350, VRB 1310 appliesdifferent levels of resistance to the force or load applied to platformsection 1350.

Platform 1350 includes a plurality of pockets 1510 into which acorresponding one of VRB 1310 are captured.

Each VRB selected resistance or suspension level provides and imparts azone of tailored bio-mechanical support to dynamically correctimbalances, e.g., Pronation/Supination/Posting of the foot, byredistributing ground reaction forces while standing, walking orrunning.

The biomechanics from each zone reacts by providing a smooth bell curveof support to dynamically and proportionally correct foot imbalance(s)to enhance foot performance per specific activity, e.g., weightdynamics, energy return from loading and unloading, cornering,sprinting, running, walking or to ease of locomotion.

FIG. 13B illustrates a perspective, underview, of a VRB footwearsuspension system 1303 in accordance with the principles of theinvention.

As illustrated, VRBs 1310 extend from platform 1350, wherein the VRBs1310 terminates in pocket 1510. Pocket 1510 captures a free end of VRB1310, while allowing the VRB 1310 to rotate from a minimum resistiveposition to a maximum resistive position. As VRB 1310 rotates from aminimum resistive position to a maximum resistive position, the heightof platform section 1350 is changed, while simultaneously altering thedegree of support or rigidity applied to the platform section 1350.

Also illustrated in this exemplary embodiment VRBs 1310 extend from afront section 1360 to platform section 1350, wherein the VRBs 1310terminate in pocket 1510. Pocket 1510 captures a free end of thecorresponding VRB 1310, while allowing the VRB 1310 to rotate from aminimum resistive position to a maximum resistive position. As VRB 1310rotates from a minimum resistive position to a maximum resistiveposition, the height of platform 1350 is changed, while simultaneouslyaltering the degree of support or rigidity applied to the platform 1350.

FIG. 13C illustrates a side view of an exemplary footwear 1300 inaccordance with the principles of the invention.

As illustrated platform 1350, positioned in a center of insole 1305 offootwear 1300, includes pockets 1510 that capture corresponding VRB 1310at a first end. VRB 1310 extends, at an angle of declination, toward, inthis illustrative example, both the front section 1360 and the heelsection 1340. Although the VRB suspension support system 1303 shownherein includes four (4) VRBs 1310, it would be appreciated that thenumber of VRBs 1310 may be increased or decreased without altering thescope of the invention.

Further illustrated is selector or adjustment mechanism 1520incorporated into pockets 1510. Adjustment mechanism 1520 providesindividual control of a corresponding VRB 1310. In this illustrativeexample, adjustment mechanism 1520 alters the orientation of VRB 1310with respect to platform section 1350 through the rotation of a gearassembly, as will be discussed. In an alternative embodiment, selectoror adjustment mechanism 1520 may be incorporated, referred to as 1521,at one or more of front section 1360 and heel section 1340.Incorporation of selector 1521 into front section 1360 and/or heelsection 1340 provides for additional types of selector mechanisms to beutilized.

FIG. 14A-FIG. 14C illustrate different degrees of support for a platformsection 1350 based on an orientation of VRB 1310 with regard to a samelevel of force (F) applied to the platform section 1350. In theseillustrate examples, selector 1521 is shown incorporated into heelsection 1340, wherein VRB 1310 extends at an angle of inclination 1410from surface 1345 to platform section 1350, wherein an end of VRB 1310is captured in pocket 1510. Although FIG. 14A-FIG. 14C illustrate only asingle VRB 1310 it would be appreciated that a second VRB 1310 mayextend from front section 1360 to platform 1350, as shown in FIG. 13A,for example.

FIG. 14A illustrates a degree of support for platform section 1350 whenVRB 1310 is in a minimum resistive position. In this case, VRB 1310 hasa minimum resistance to force F applied to platform section 1350, suchthat VRB 1310 may have a maximum deviation from an angle of inclination1410 of VRB 1310 measured with respect to heel surface 1345.

FIG. 14B illustrates a degree of support for platform section 1350 whenVRB 1310 is in a position between a minimum resistive position and amaximum resistive position. In this case, VRB 1310 has a mid-levelresistance to force F applied to platform section 1350, such that VRB1310 may have a mid-range deviation from an angle of inclination 1410 ofVRB 1310 measured with respect to heel surface 1345.

FIG. 14C illustrates a degree of support for platform section 1350 whenVRB 1310 is in a maximum resistive position. In this case, VRB 1310 hasa maximum resistance to force F applied to platform section 1350, suchthat VRB 1310 has a minimum deviation from an angle of inclination 1410of VRB 1310 measured with respect to heel surface 1345.

As shown in FIG. 14A-FIG. 14C, a height 1430 of platform section 1350may be altered based on the orientation of VRB 1310 with respect to theplatform section 1350 and heel section 1340.

In another aspect of the invention, a height 1430 of platform section1350 may be determined based the angle of inclination 1410 of VRB 1310with respect to surface 1345 (or with regard to an angle of declinationfrom attachment plate 1510). In a preferred embodiment, the angle ofinclination 1410 of VRB 1310 with respect to a surface 1345 is in therange of 1 degree to 45 degrees. As would be recognized, the angle ofinclination of VRB 1310 contributes to the height of platform section1350 and to the resistance of VRB 1310 to a force applied to platformsection 1350.

FIG. 15A illustrates a perspective view of an exemplary secondembodiment of a VRB footwear variable resistance and suspension system1303 in accordance with the principles of the invention.

In this illustrated embodiment, two VRBs 1310 are shown supportingplatform section 1350 under force plate 1305. In this illustratedembodiment, two VRBs 1310 are positioned on a left side and a right sideof platform section 1350. Application of multiple VRBs 1310 provides forsymmetric or asymmetric support of a force applied to platform section1350. Although two VRBs 1310 are shown, it would be appreciated thatadditional VRBs 1310, extending toward the front of force plate 1305 maybe incorporated without altering the scope of the invention.

Also shown are corresponding entry points 1530 that allow access toadjustment mechanisms 1520, which provide individual control of acorresponding VRB 1310. In this illustrative example, adjustmentmechanism 1520 alters the orientation of VRB 1310 with respect toplatform section 1350 through the rotation of a gear assembly, as willbe discussed with regard to FIG. 17A-FIG. 17C, for example.

In the configuration shown, support provided by the VRB 1310 under theplatform section 1350 may be adjusted to be firmer on one side thansupport provided by the VRB 1310 the other side to provide a customizedlevel of support.

Also illustrated is heel plate 1560 that may be incorporated into VRBfootwear variable resistance and suspension system 1303. Heel plate 1560provides additional support for heel 1340 and determines an angle ofinclination of VRB 1310.

FIG. 15B illustrates a perspective view of an exemplary embodiment of aVRB footwear variable resistance and suspension system 1303 inaccordance with the principles of the invention.

In this illustrated embodiment, VRB 1310 extend from correspondingpockets 1510 attached to platform section 1350. Platform section 1350 ispositioned substantially centered in insole 1305 in footwear 1300. Alsoillustrated are selectors or adjustment mechanisms 1520 incorporatedinto pockets 1510. As discussed, selectors 1520 provide for rotation ofVRB 1310 with respect to attachment plate 410.

Further illustrated are pads 1570 which include pockets (not shown) thatcapture a free end of a corresponding VRB 1310. Pads 1570 provide forthe containment of the VRB footwear variable resistance and suspensionsystem 1303 within footwear 1310, without any exposure (FIG. 15A,element 1530) to an outside environment.

Also shown is platform section 1350 being in a shape of an “X.” As wouldbe appreciated platform section 1350 may also be shaped flat, contoured(see FIG. 15A) or conformed to a user, without altering the scope of theinvention.

FIG. 16A illustrates a perspective view of an exemplary embodiment of aVRB suspension support system 1303 in accordance with the principles ofthe invention.

In this illustrated embodiment VRB 1310 extend, at a known angle ofinclination with respect to heel plate 1560 and front plate 1605 towardsplatform section 1350. As previously discussed, platform section 1350includes pockets 1510 (not shown) that capture a free end ofcorresponding VRB 1310. Furthermore, selector 1520 may be incorporatedinto pockets 1510 or may be incorporated (i.e., selector 1521) into heelplate 1560 and/or front plate 1605 (see FIG. 15A).

In one aspect of the invention, plate of platform section 1350 may becustomized to be provide individualized support. As would beappreciated, plate 1350 may be flat, conformed and/or customized withoutaltering the scope of the invention.

As is further shown, VRB 1310 may be contained within a substantiallycircular housing, sleeve or sheathing 1312. Housing 1312 enables VRB1310 to rotate substantially uniformly from a minimum resistanceposition to a maximum resistance (or support) position. In one aspect ofthe invention, the VRB 1310 may rotate within sheathing 1312, whereinsheathing 1312 is fixed. In another aspect of the invention, VRB 1310may be attached to sheathing 1312 and as sheathing 1312 rotates, thecontained VRB 1310 rotates.

As will be discussed with regard to FIG. 22A-FIG. 22F, VRB 1310 maypossess an elongated shape having a major axis greater than a minoraxis, which is substantially perpendicular to the major axis.

FIG. 16B illustrates a side view of an exemplary embodiment of afootwear 1300 incorporating a VRB suspension support system 1303 asshown in FIG. 16A.

In this exemplary embodiment, VRB suspension support system 1303,positioned substantially center of insole 1305 of footwear 1300 includesplatform section 1350, VRBs 1310 extending from pockets 1510, throughsleeves 1312, to corresponding heel plate 1560 and front plate 1605, ata known angle of declination (or angle of inclination with regard toheel surface 146 and a surface of front section 1360). As would beappreciated, the angle of inclination may be the same or different foreach of the illustrated VRBs 1310.

Also illustrated is an alternate embodiment, wherein front plate 1605and heel plate 1560 include opening elements 1530 (see FIG. 15A), whichallow selector 1521 to be incorporated into front section 1360 and heelsection 1340, respectively.

FIG. 17A-FIG. 17C illustrate end views of VRB 1310 including aspects ofa first embodiment of an adjustment mechanism for altering theorientation of the VRB 1310.

FIG. 17A illustrates an example of an end of VRB 1310, which isaccessible through heel section 1340, for example, that includes threecircular cut-outs or indentations 1380 formed in a triangular pattern.Insertion of a tool (e.g., a screw driver) matching the indentationpattern 1380 allows for the rotation of VRB 1310.

Although indentations 1380 are shown in a triangular pattern, it wouldbe recognized that the indentations 1380 may be arranged in any patternthat allows rotation of VRB 1310 to change the orientation of its majoraxis with respect to heel surface 1345.

FIG. 17B illustrates a second example of an end of VRB 1310 thatincludes a diamond shaped indentation 1385. In this case Insertion of atool (e.g., a screw driver) matching the diamond shaped indentationpattern 1385 allows for the rotation of VRB 1310 to change theorientation of its major axis with respect to heel surface 1345.

FIG. 17C illustrates a third example of an end of VRB 1310 that includesa Philips (or cross) pattern. In this case Insertion of a tool (e.g., ascrew driver) matching the Philips (or cross) indentation pattern 1390that allows for the rotation of VRB 1310 to change the orientation ofits major axis with respect to heel surface 1345.

The selector or adjustment mechanism shown in FIG. 17A-FIG. 17C may besuitable for use as selector 1521, wherein access to the end of VRB 1310may be obtained through entry point 1530.

FIG. 18A-FIG. 18F illustrate exemplary aspects of a second exemplaryembodiment of an adjustment mechanism in accordance with the principlesof the invention.

FIG. 18A illustrates an exemplary adjustment mechanism represented by aworm gear 1830, which engages a gear 1815 that is incorporated on asubstantially circular gear head 1810 to which VRB 1310 is attached.Worm gear 1830 may include an adjustment means (such as an indentation1860, which may capture an Allen key, Torx key, a Philips tip, forexample, as shown in FIG. 17A-FIG. 17C). Insertion of the Allen key intoindentation 1860 and rotation of Allen key causes rotation of worm gear1830. As worm gear 1830 rotates, the rotation of worm gear 1830 istransferred to the gear 1815 of head 1810 causing the rotation of VRB1310.

FIG. 18A further illustrates a locking plate 1820. Locking plate 1820retains worm gear 1830 (and consequentially VRB 1310) in a lockedposition, as will be discussed.

As would be appreciated as VRB 1310 rotates from a minimum resistanceposition, corresponding to minor axis position, to a maximum resistanceposition, corresponding to major axis position, support to platform 1350increases from a minimum to a maximum.

FIG. 18B illustrates a top view of worm gear assembly 1850 includingworm gear 1830 and locking plate 1820. Further illustrated is screw(e.g. a set screw) 1825 that alters the position of locking plate 1820with respect to worm gear 1830.

In one aspect of the invention, as shown in FIG. 18B, assembly 1850includes a threaded opening 1861, through which passes set screw 1825 toengage locking plate 1820. As set screw 1825 is rotated in a firstdirection, locking plate 1820 is moved toward worm gear 1830. Lockingplate 1820 further includes a toothed surface opposite screw threads1835 of worm gear 1830. As locking plate 1820 advances towards worm gear1830, the toothed surface of plate 1820 engages screw threads 1835 ofworm gear 1830. In this position, worm gear 1830 is locked in position.Thus, the position of the VRB 1310 is fixed at that position to whichVRB 1310 has been rotated by the rotation of worm gear 1830.

In another aspect of the invention shown in FIG. 18C, as screw 1825 isrotated in an opposite direction, the toothed surface of locking plate1820 is withdrawn from screw threads 1835 and worm gear 1830 is free torotate. In this manner, locking plate 1820 moves inward or outward alongscrew 1825 as screw 1825 is rotated. The position of locking plate 1820may be altered by the insertion of an adjusting means, such as an AllenKey, a Philips screwdriver, etc., in screw hole 1860 to engage screw1825.

FIG. 18D illustrates a planar view of exemplary embodiment of the wormgear assembly 1850 in accordance with the principles of the invention.In this exemplary embodiment, locking plate 1820 engages screw threads1835 of worm gear 1830. Also illustrated is gear head 1810 engagingscrew threads 1835. Gear head 1810 may be attached to VRB 1310, whichenables VRB 1310 to rotate within sheathing or sleeve 1312.Alternatively, gear head 1810 may be attached to sheathing 1312 to allowrotation of VRB 1310.

FIG. 18E illustrates a planar view of footwear 1300 including platformsection 1350 incorporating the gear assembly 1850, shown in FIG.18A-FIG. 18D, in heel section 1340. Assembly 1850 includes gear 1830,which engages gear head 1810 attached to VRB 1310. VRB 1310 is capturedin pocket 1510, as previously described.

Further illustrated is a conventional Philips tip screw driver 1890 thatmay be used to rotate gear 1830 by insertion of the Philips tip intoindentation 1860, which is shaped in a manner similar to that shown inFIG. 17C.

Although a conventional Philips tip screw driver 1890 is illustrated, itwould be appreciated that indentation 1860 may comprise a proprietaryshape requiring a corresponding proprietary tip similar to those shownwith regard to FIG. 17A-FIG. 17B.

Although a single VRB 1310, it would be appreciated that a plurality ofVRBs 1310 may be incorporated in the support system 1302, as shown inFIG. 15B, for example.

FIG. 18F illustrates a side view of footwear 1300 including platformsection 1350 wherein indentation 1860 is shown having a cross shape thatengages the tip of Philips screw driver 1890.

As previously discussed, as gear 1830 is rotated, VRB 1310 is rotatedthrough the engagement of gear head 1810 with gear 1830.

The selector or adjustment mechanism shown in FIG. 18A-FIG. 18F may besuitable for use as selector 1520 and selector 1521, wherein access tothe adjuster 1860 is through a side of pocket 1510 or a side of heelsection 1340.

FIG. 19A-FIG. 19D illustrate aspects of a third exemplary adjustmentmechanism for controlling rotation of a VRB utilized in the footwear1300 shown in FIGS. 13A and 13B, for example.

FIG. 19A illustrates a perspective view 1900 of a third exemplaryconfiguration of a control or adjustment means in accordance with theprinciples of the invention.

In this exemplary configuration, referred to herein after as“spline/socket”, a manual, geared, mechanism selectively rotates VRB1310 in controlled increments ranging from 0° to 90° whilesimultaneously controlling torque.

As shown, the socket/spline 1900 provides an adjustable locking systemthat secures a VRB 1310 from rotation and therefore mechanicallymaintains a constant resistance or suspension.

VRB 1310 further includes a fork or tongue 1910 that is insertable intospline 1920. Spline 1920 is a substantially round, solid, rod includingtongue or fork 1925. Tongue or fork 1925 engages (and matches) tongue orfork 1910 of VRB 1310.

Also shown is socket 1930 into which spline 1920 is inserted. Socket1930 contains fork 1925 and tongue 1910 in a manner such that as spline1920 is rotated, VRB 1310 is similarly rotated.

At a proximal end of socket 1930 is shown grooves 1935 and splineelements 1945 formed between adjacent ones of grooves 1935. In oneaspect of the invention, the spacing of spline elements 1945 (grooves1935), provides for a desired locking rotation. For example, 16 splineelements 1945 provide for 22.5° of incremental VRB 1310 rotation.(360°/16=22.5°).

In accordance with the principles of the invention, VRB 1310 plus spline1920 form an adjustable assembly, wherein the spline element 1920 maybepulled out by grasping spline head 1940, rotating the spline element1920 and re-inserting the spline 1920 into socket 1930, to provide ahigher or lower resistance or suspension level. This level of resistanceis dependent upon the rotation VRB 1310.

Also illustrated is faceplate 1950. Faceplate 1950 includes an indiciaof the degree of rotation of VRB 1310.

As would be appreciated, tongues or forks 1925 and 1910 are sized sothat they remain engaged, even when spline 1920 is pulled out, turnedand re-inserted into socket 1930.

FIG. 19B illustrates a perspective view of spline 1920. In thisillustrative embodiment, spline 1920 is a substantially cylindrical rodincluding at a first end fork 1925 and a spline head 1940 on a secondend. Further illustrated are spline elements 1945 positioned about acircumference of spline 1920 between adjacent ones of grooves 1935.

As shown, a length of fork 1925 is sufficiently greater than a length ofspline elements 1945 in order to prevent spline 1920 from disengagingVRB 1310 (not shown) when spline 1920 is pulled from socket 1930

FIG. 19C illustrates a perspective view of a spline element 1945 ofspline 1920 engaging grooves 1932 of socket 1930. In this illustrativeexample, socket 1930 includes a plurality of grooves 1932 and splineelements 1934 between adjacent ones of grooves 1932. Grooves 1932 andspline elements 1934 of socket 1930 match in number and width withspline element 1945 and grooves 1935.

As discussed, spline 1920 may be withdrawn from socket 1930, rotated andreinserted into socket 1930. The rotated and reinserted spline 1920alters the position of the VRB 1310 (not shown) such that a differentlevel of rigidity of VRB 1310 may be achieved (see FIG. 14A-FIG. 14C).The engagement of spline elements 1945 with grooves 1932 lock and retainVRB 1310 (not shown) in a desired position.

FIG. 19D illustrates a perspective view of a control mechanism 1900illustrating VRB 1310 engaging fork 1925 in spline 1920 in accordancewith the principles of the invention.

In this illustrative embodiment, VRB 1310, which is shown having arectangular cross-section, includes tongue 1910 that may be insertinginto fork 1925 in order to provide a secure connection between tongue1910 and fork 1925, as previously discussed.

Further illustrated is retaining ring 1970. Retaining ring 1970represents a spring loaded mechanism that enables spline head 1940 to bewithdrawn from socket 1930 by pushing spline head 1940 into socket 1930.The act of pushing spline head 1940 into socket 1930 disengagesretaining ring 1970 and the spring loaded mechanism forces spline head1940 to withdraw from socket 1930. In one aspect of the invention,retaining ring 1970 may be constructed of a spring-able material andshaped to operate as the spring mechanism.

Further illustrated are pins 1980, which when inserted into holes 1985provide a secure connection between fork 1925 and tongue 1910.

As would be appreciated holes 1985 may be elongated in order to allowspline head 1940 to be withdrawn from socket 1930 a limited distance. Inthis case, spline head 1920 may not be totally withdrawn from socket1930 (not shown) even if spline head 1940 is inadvertently pushed in.

The selector or adjustment mechanism shown in FIG. 19A-FIG. 9C may besuitable as selector 1521, wherein access to the end of VRB 1310 may beobtained through entry point 1530 (see FIG. 15, element 1530).

FIG. 20A(a) illustrates a planar view of an exemplary variableresistance and suspension system 1303 in accordance with the principlesof the invention. In this illustrative embodiment, the VRB configurationincludes an adjustment mechanism similar to that shown in FIG. 19A,wherein the VRB 1310 may be rotated in discrete intervals. It would,however, be appreciated, that the adjustment mechanism shown in FIG.17A-FIG. 17C or FIG. 18A-FIG. 18F may similarly be utilized withoutaltering the scope of the invention.

As shown bio-sensor 2030 may be incorporated onto the platform 1350 offootwear 1300. Incorporation of bio-sensor 2030 provides for aprognostic and injury avoidance capability to measure a mechanicaldeflection of dynamic loads being exerted on a body joint or structure.This is principally achieved through the monitoring of the flexing shapeof a VRB (Variable Resistance Beam) or multiple VRBs as loads aredynamically applied, quantified and recorded with the wearer notified ofloading conditions that would exceed the joints physical ability sustainnormal operation without damage, e.g. repetitive strain. Thus,measurement of dynamic joint loading over time provides a real timehealth monitoring and predictive system to prevent or treat injury.

A few examples of physical sensors 2030 to measure and quantify jointstress, strain loading cycles, and/or changing suspension supportrequirements are Thin Films, Wheatstone Bridges (metal foil sensorstructures), potentiometers, temperature gauges, pressure gauges, foils,piezo-resistors, semiconductors, nano-particulates, conductivenano-layers, silver nanowire, Graphene, e.g. graphene imbued rubberbands: flexible, low-cost body sensors, such as nanoelectromechanicaldevices, piezoresistive devices, conductive electroplating, diffractiongrating, optical fiber, optical grid (Non-Intrusive Stress MeasurementSystem—NSMS), wire, micro tubes, miniature WiFi transmitters,accelerometers, load cells and or other means to detect VRB flexure ormovement of any kind.

Physical sensing of the application of a force or strain occurs when oneor more VRBs 1310 is deflected or flexed. As the physical shape of theVRB is deformed, an electrical resistance changes. Similarly othermeasurement quality(ies) or physical parameter(s), e.g. optical,physical location or acceleration, are similar effected.

For example, the Wheatstone bridge illustrates the concept of adifference measurement, which can be extremely accurate. Variations onthe Wheatstone bridge can be used to measure capacitance, inductance,impedance and other quantities to calculate total potential movementover time.

Although FIG. 20A(a) illustrates the placement of bio-sensor 2030 onplatform, placement and locations of the bio-mechanic sensors 2030 maybe bonded onto or along the surface length of VRB 1310, into a sidechannel and/or internally through an interior diameter hole, bore and orextruded geometry to accept and hold the sensor. (see for example,element 2030′). FIG. 20B illustrates exemplary placement of sensors 2030on or within VRB 1310.

FIG. 20A(b) illustrates a side view of an exemplary placement of a PCB2030 on platform 1350.

In another aspect a strain gauge may be incorporated in which advantageis taken of the physical property of electrical conductance and itsdependence on the conductor's geometry. For example, when an electricalconductor is stretched within the limits of its elasticity withoutpermanent deformation, the sensor will become narrower and longer. Thischanges or increases the electrical resistance along the sensors lengthor end to end. Silver nanowire is an excellent example of an electricalconductor with a 150% stretch limit while measuring conductivity withfidelity.

When measuring electrical resistance of a strain gauge bonded to a VRB1310, the amount of applied stress may be inferred. As an example,another typical strain gauge arranges a long, thin conductive strip in azig-zag pattern of parallel lines such that a small amount of stress inthe direction of the orientation of the parallel lines results in amultiplicatively larger strain measurement over the effective length ofthe conductor surfaces in the array of conductive lines—and hence amultiplicatively larger change in resistance—than would be observed witha single straight-line conductive wire.

Other methods of sensing VRB deflection, range from temperature (kineticheating), piezo (milli-voltage generation), electromagnetic sensing,optical sensing (diffraction grating), to miniature WiFi signallingphysical location and or accelerometer chips.

As would be recognized one or more of the described sensors, herein, maybe incorporated into the illustrative sensor 2030 (or 2030′). Allsensors may directly wired and connected to a physical circuit. Or bymeans of a wireless signal to an embedded printed circuit board (PCB)with processing algorithm, battery and transmitter information regardingthe flex and/or stress detected may be processed (using one or morealgorithms) on the PCB and the results forwarded to a remote receiver(i.e., handheld or worn) to alert the wearer to potential injury orcurrent physical condition. Similarly, the measured parameters (i.e.,raw data) may be provided to a remote receiver for subsequentprocessing.

In another aspect of the invention, with the addition of accelerometermicrochips, e.g. similar to ones used in smartphones/tablets/watches orsuch devices, 360° X Y Z axial data is produced and therefore a moreinformative and prescriptive biomechanic measurements may be captured towarn of impending injury and inform the wearer whether the feet areincreasingly pronating or supinating mechanics.

An accelerometer chip interfaced with one or more biosensors 2030 mayprovide further prescriptively diagnose of the body joint condition,i.e. foot, by using quadrant data of the foot to compare and contrastbody weight loading (history) and changing weighting dynamics per zone.Specifically, this quadrant data of weight loading combined with anaccelerometer chip detecting movement in 360° X Y Z axes may determinewhether an injury or foot condition is worsening, progressing to injury,failure, as well as monitor and quantify podiatry foot conditions, e.g.heel posting.

This data would be central to the diagnosis, treatment and physicaltherapy. Measurement of the parameters associated with the application aforce to the variable resistance and suspension system 1303 shown inFIG. 13A, for example, may be customized and tailored to eachindividual's support requirement and notably reduce atrophy by allowingthe wearer degrees of movement.

FIG. 21 illustrates an exemplary configuration of a handheld device 2190communicating with one or more sensors 2030 (2030′) incorporated intothe variable resistance and suspension system 1303 shown in FIG. 13A,for example.

As would be appreciated communication between sensors 2030 (2030′) maybe through a short range communication protocol, such as BLUETOOTH, NFC,etc.

In one aspect of the invention, the VRB 1310 mechanical movement may becaptured by piezo, dynamo (polyphase AC/DC electric motor), hydraulic orother mechanism to capture and store mechanical energy from the VRBflexing or footwear shell cyclical compression during walking. Thissystem may be used as a battery recharging system using a device capableof capturing mechanical movement and converting the mechanical movementinto electrical energy. For example, piezo-material or PvF2(PolyVinylidene Fluoride 2) may be incorporated into the VRB assembly tocreate a battery recharging system and/or a heel cushion to absorbbodyweight impacts via shock absorbing diaphragm. Additionally, part ofthe energy generated would be used to transmit the bio-sensor data to awearable device (2190, FIG. 21) to inform the wearer in real time of thecondition of their body joint condition, i.e. left or right foot.

In another aspect of the invention, the recharging system may also beconnected to and provide energy to drive a worm gear servo to change theVRB resistance setting to prescriptively support the body jointcondition in response to the bio-sensor data. This closed looped systemprovides a prescriptively corrective, rehabilitative, prophylactic orpreventative support system for a body joint or extremity, e.g. foot, byincreasing and/or decreasing the support imparted. The closed data loopsystem consists of a flexing VRB 1310 to biomechanically support a bodystructure or joint bonded to a Biosensor whose data stream is connectedto an ‘onboard PCB’ (printed circuit board). The biosensor data signalis received, transmitted and stored onto the PCB to produce an algorithmoutput. The closed data loop system is sustained by a mechanism tocontinually charge a battery and/or supply electricity to charge thesystem. An advanced version of this charging system could be employed toautomatically instruct a worm gear servo to change the VRB supportlevels (lower or higher) per biosensor diagnostic algorithm data stream.

In another aspect of the invention additional means of creatingself-adjusting footwear shell geometry may incorporate the use ofprogrammable smart materials, such as carbon fiber, nitinol wire mesh,smart, self-morphing filaments, e.g. wood, or composite materialsdesigned to become highly dynamic in form and function, specificallywhen a electric charge is applied or other shaping factors.

FIG. 22A-FIG. 22F illustrate cross-sectional views of exemplaryembodiments of a VRB in accordance with the principles of the invention.The VRBs, presented as resilient rods, beams or shafts, may be composedof solid, semi-solid or hollow construction in accordance withembodiment the principles of the invention. The VRB technology comprisesa major and minor axis, which produces variable resistances whenorientated in a direction of x, y, z plane or combination of planes in360 degrees of rotation, bending movement.

FIG. 22A represents a Type II I-Beam configuration 2210 that includesone of: a static outside and internal diameter geometry or combination,thereof. The Type II I-Beam cross section geometry produces proportionaladjustable resistance according to a rotated orientation creating arelationship between an orientation and a resistance.

FIG. 22B represents a Type III Dual I-Beam configuration 2215 thatincludes inner and outer I-Beam tubes with inner and/or outer geometryor combination thereof to create variable I-beam resistance.

FIG. 22C represents a Type IV Conical beam configuration 2220 thatincludes hollow, additive or subtractive wall geometry. Conical Beamcross section geometry produces proportional adjustable resistanceaccording to a rotated orientation.

FIG. 22D represents a Type V Ellipsoidal beam configuration 2225 thatmay be a solid, a semi-solid or a hollow beam with or without outsideand/or internal diameter geometry or a combination, thereof along itsmajor axis, thus, generating additional I-beam mechanics and/orsubtractive, e.g., conical hollow, geometry along its minor axis.Ellipsoidal beam with a major axis that is wider than the minor axiswith or without internal or external geometry along the major axis.

FIG. 22F represents a Type VII Rectangular beam configuration 2235 thatincludes two sides wider than the remaining two sides.

VRB 1310, which may be solid, semi-hollow or hollow, with or withoutgeometrically created I-beam effect (i.e., asymmetric geometry, spines)on the outside or interior diameter generates resistance depending onthe axis of orientation and/or a fulcrum position has been describedherein. A VRB 1310, with incorporated I-beam geometry on the outsidediameter, may allow for the dynamic adjustment of resistance of thedevice. An advantage of a device including VRBs described herein may becompact, lightweight and offer the ability to more easily and quicklychange a desired level of resistance than is typically found in unitsusing weights, rubber bands, bows or springs. By simple reposition orrotation of a VRB incorporated into the device, a desired selectablerange of resistance level may be achieved. The VRBs 1310 disclosed,herein, can provide resistance, depending on the orientation of thebeam, to a bending direction. In addition, an exemplary deviceincorporating the VRB technology may vary the resistance provided to theuser during rehabilitative exercise, without interrupting the exercisecycle. Additional beam resistance is achieved depending upon therelative orientation of the beam within a 180° degree hemisphere ofmovement relative to the user.

Hence, according to the principles of the invention, a progressivedynamic resistance may be achieved with a variation of the orientationof the beam or shaft shown herein.

In one aspect of the invention, rods with symmetrical cross sectionsvary their bending resistance by shortening and lengthening the arclength, from fulcrum to anchor point by hand position per indicia.

In another aspect of the invention, rods with asymmetrical crosssections may increase or decrease their bending resistance by rotationof the elongated orientation with respect to a bending force, whilemaintaining the same hand adjusted position or fulcrum length.

In one aspect of the invention, the VRBs 1310 may be composed ofthermoplastic polymers, especially high tenacity polymers, include thepolyamide resins such as nylon; polyolefin, such as polyethylene,polypropylene, as well as their copolymers such as ethylene-propylene;polyesters, such as polyethylene terephthalate and the like; vinylchloride polymers and the like, and polycarbonate resins, and otherengineering thermoplastics such as ABS class or any composites usingthese resins or polymers. The thermoset resins include acrylic polymers,resole resins, epoxy polymers and the like.

Polymeric or composite materials may contain reinforcements that enhancethe stiffness or flexure of the flexure resistance spine. Somereinforcements include fibers, such as fiberglass, metal, polymericfibers, graphite fibers, carbon fibers, boron fibers and

Nano-composite additives, e.g., carbon nano-tubes, et al., to fill themolecular gaps, therefore strengthening the material.

Additional materials that the resistance rods or VRBs 1310 may also becomposed of include high tensile aircraft aluminum and high carbonspring steel and/or high tensile strength to weight materials.

FIG. 12 illustrates an exemplary medical brace in accordance with theprinciples of the invention. In this illustrative example, at least oneVRB 100 is incorporated into a VRB assembly 1215 into an anchor 1230, anadjuster 1220, and a fulcrum 1210. The bracing system in FIG. 12 iscomprised of a thigh leg strap collar 1205 attached to a frame with afulcrum 1210 connected to a hinge 1225 with an upper arm 1240 with abushing piston acting as a second cartilage.

In this illustrative embodiment, VRBs 100 are adjusted to create avariable flex. Element 1205 illustrates leg strap or collar (thigh).Element 1205 a illustrates leg strap or collar (calf). Element 1210illustrates fulcrum for VRB to maintain controlled bending. Element 1215illustrates a VRB assembly (one or more VRB's) that acts as aleaf-spring/unloader; i.e., a first suspension point. Element 1220illustrates VRB assembly adjuster to customize flexibility orresistance. The assembly adjuster 1220 may be a worm gear as previouslydescribed. Element 1225 illustrates a hinge that mimics thebio-mechanical movement or range of an anatomical joint (e.g. knee).Element 1230 illustrates VRB assembly anchor with spring/bushings: i.e.,a secondary suspension point. Element 1240 illustrates a telescopingupper hinge arm with a bushing piston, a second cartilage: i.e., a thirddampening or cushioning point. VRB assemblies 100 a or 1215 provides adynamic supportive structure designed to act as an artificial or secondknee to support a damaged or injured one.

An additional benefit of incorporating the VRB 100 technology intomedical devices is that the resistance rods, under compression, create aproportioned constant vertical lift to unload 1215 and dynamicallysupport the joint (e.g., a knee) during post op, rehabilitation,arthritis or during extreme sports. Hence, the VRB 100 technologydescribed herein provides a truly functional and adjustable brace thatprovides for Shock Absorbing 1215, 1230, 1240, Active Suspension 1215,Adjustable Comfort DST Unloader Knee Brace.

As previously described, resistance ranges are generated by rotating thebeams over a fulcrum positioned adjacent to a body joint.

Dynamic support is also beneficial for the recuperative period followingoperation, rehabilitation, arthritis or during extreme sports.Additionally, resistance beam assemblies may also contribute to shockabsorption via a bushing and piston arm mechanically connected to thebeam assembly. Furthermore, beam assemblies positioned on each side of ajoint act as lateral stabilizers.

FIG. 23A illustrates a further example of the incorporation of a VRB 100into a running or athletic shoe 2300 (similar to 1300, FIG. 13A) inaccordance with the principles of the invention.

In this illustrated embodiment, the shoewear 2300 includes an uppersection and a lower or sole section 2310 that are formed together.Further illustrated are a plurality of footwear module or adjustableplatforms 2305, wherein one platform is positioned, within the solesection 2310, a forward portion, before the foot arch section 2307, andone is positioned aft of the foot arch section 2307. The footwear moduleor adjustable platform 2305 is composed of a VRB 100 (referred tohereinafter as 2320 (and is similar to form and characteristics as thatdescribed with regard to VRB 100 (and 1310) in FIG. 1A-FIG. 1G. VRB 2320further includes a threaded end section 2360. Further illustrated is ananchor plate 2330, which includes a containment pocket or socket 2370.The containment pocket 2370 includes an internal thread. The containmentpocket may be a separate section attached to the anchor plate or may beconformally formed as a part of the anchor plate 2330. The threaded endsection 2360 of VRB 2320 engages the internally treaded socket or pocket2370 such that VRB 2320 is rotatable within the threaded socket 2370.

Although a plurality of footwear module or adjustable platforms 2305 areshown, it would be appreciated that the shoewear 2300 may comprise asingle footwear module or adjustable platform 2305 without altering thescope of the invention.

As is further illustrated the footwear module or adjustable platforms2305 may be oriented within the sole 2310 such that an angle oforientation of the footwear module or adjustable platform 2305, withrespect to a surface upon which the shoewear 2300 rests may be set atany desired angle. As shown, the rear footwear module or adjustableplatform 2305 is essentially parallel to the surface while the forwardfootwear module or adjustable platform 2305 is set at an angle ofapproximately 20 degrees.

However, it would be understood that the angle of orientation of afootwear module or adjustable platform 2305 may be set as shown in FIG.14A-FIG. 14C, wherein a height of the VRB 2320 above the surface may bealtered, FIG. 23B illustrates a bottom view of the shoewear 2300 furtherillustrating the arrangement of the VRBs 2320 and anchor plate 2330 inaccordance with the principles of the invention.

In this illustrated embodiment, each footwear module or adjustableplatform 2305 is composed of two VRBs 2300 extending from acorresponding anchor section 2330. The anchor sections 2330 reside oneither side of the shoe arch section 2307 and the VRBs extend form thecorresponding anchor section toward the forward and back of the shoewearrespectively.

Further illustrated are access nodes 2350 within sole 2310. Access nodes2350 allow a user to gain access to a corresponding VRB 2320 so as torotate the VRB 2320 and, thus, adjust the level of flex (or resistance)the VRB 2320 possesses in response to a downward force applied by theshoewear (see FIG. 14A-FIG. 14C, for example).

Although the access nodes 2350 are shown under the shoe 2310, it wouldbe recognized that the access nodes 2350 may be positioned in a manneras shown in FIG. 13C, wherein the access nodes 1530 are used to obtainaccess to the VRBs are arranged along a side of the sole 2310.

Also illustrated is an angle of orientation (α) of the VRBs 2310, withina same anchor plate 2330, with respect to each other. The angle oforientation is selected to provide a stable platform for the shoewear tolimit an amount of twisting experienced by the shoewear with an unequalapplication of force of the footwear module or adjustable platform 2305.In one aspect of the invention, the angle of orientation may be selectedas zero (0) degrees i.e., substantially parallel VRB orientation).However, the angle of orientation may be selected, based in part on thelength of the VRB 2320 and the width of the shoewear to substantially 45degrees.

FIG. 24A illustrate an exemplary VRB 2320 including a threaded or helixend section 2360. As previously discussed the VRB 2320 is equivalent tothe VRB 100 and possesses the shapes and characteristics previouslydiscussed.

FIG. 24B illustrates an exemplary anchor section 2330 including thethreaded pockets 2370. The thread pitch of pocket 2370 is comparable tothe thread pitch of thread section 2360. As would be recognized thedegree of rotation of the VRB 2320 is determined based on the threadpitch. As discussed, the rotation of VRB 2320 alters the resistance ofthe VRB to a downward force applied by a user, for example, wearing theshoewear.

Returning to FIG. 23A, further illustrated is a wrap element 2425 thatmay be optionally placed around the thread section 2360. The wrapelement 2425 may be of a material that compensates for anyirregularities between the thread section 2360 and the internal threadwithin threaded pocket 2370. The wrap element 2425 may further allow fora frictional force to retain VRB 2320 in a set position.

FIG. 24C illustrates a completed footwear module or adjustable platform2305, in accordance with the principles of the invention, wherein thethreaded section 2360 of a corresponding VRB 2320 is inserted in acorresponding threaded pocket 2370 of angle 2330. In this case the angleof orientation (a) between the VRBs 2320 is set by the angle of threadedpockets 2370 of the anchor 2330.

FIG. 25A illustrates a bottom view of the completed footwear module oradjustable platform 2305, similar to that shown in FIG. 24C. Furtherillustrated is an adjustment tool 2510 which is insertable into an openend 2520 (not shown) of threaded pocket 2370. The adjustment tool 2510enable a user to alter the orientation of the VRB 2320, as has beendiscussed previously.

FIG. 25B illustrates a side view of the footwear module or adjustableplatform 2305 shown in FIG. 25A, wherein the adjustment tool 2510engages an end of VRB 2320 through open end 2520. Although adjustmenttool 2510 is shown in a key shape it would be appreciated that theadjustment tool 2510 may be of any shape, such as a screwdriver.

Although not shown, in FIG. 25B, the end of VRB 2320 includes anindentation that allows the adjustment tool 2510 to engage the VRB 2320in order to turn the VRB 2320. For example, the indentation within theend of the VRB 2320 may be similar to those disclosed with regard toFIG. 17A-FIG. 17C. In addition other indentation shapes have beencontemplated and are considered to be within the scope of the invention.

FIG. 25C illustrates an end view of VRB 2320, which in this illustratedexample is shown with an elliptical shape (see Type V bar, FIG. 1E).Further illustrated is thread 2540 circumventing VRB 2320. In thisillustrated example, the treaded section 2370 is a substantiallycircular configuration (similar to that shown in FIG. 18A). It would beunderstood that threaded pocket 2370 would be of a similarconfiguration. Further shown is indentation 2530, which is substantiallysemi-elliptical or elongated semi-circular shape. The orientation of thesemi-elliptical shape in this case provides an indication of theorientation of the VRB 2320. That is, as the semi-elliptical indent isaligned with the major axis of the VRB 2320, the orientation of theindent provides an indication of the orientation of the major axis and,hence, the degree of resistance the VRB 2320 possesses with respect to aforce applied to the shoewear. That is FIG. 25C illustrates a maximumresistance, while FIG. 25D illustrates a minimum resistance.

Although FIG. 25C and FIG. 25D illustrate a substantially circularthreaded section 2360, it would be recognized that the treaded section2360 may be incorporated directly on the VRB 2320 and the threadedsection 2360 would engage the threaded pocket as previously discussed.In this case, any non-conformity between the shape of the threadedsection 2360 and the pocket 2370 may be compensated for with wrapping2510 as previously discussed.

FIG. 26A illustrates a second embodiment of a footwear module oradjustable platform 2605 in accordance with the principles of theinvention. In this illustrated embodiment, the footwear module oradjustable platform 2605 is comprised of a plurality of footwear moduleor adjustable platforms 2305 and a flexible membrane 2610 joining theplurality of footwear module or adjustable platforms 2305. Theorientation of the footwear module or adjustable platforms 2305 issimilar to that shown in FIG. 23A, and as previously discussed may beselected based on the previously discussed criteria.

FIG. 26B illustrates a bottom view of a footwear module or adjustableplatform 2605 shown in FIG. 26A. As shown a flexible membrane 2610,positioned under the arch section 2307 of the shoewear 2300, joins thetwo footwear module or adjustable platforms 2305. The flexible membrane2610 provides further resistance force as a force is applied to thefootwear and provides a restoring force to return the footwear to itsoriginal configuration when the applied force is removed.

FIG. 26C illustrates a side view of the footwear module or adjustableplatform 2605 shown in FIG. 26A and FIG. 268.

In this illustrated example, the footwear module or adjustable platforms2305 and the flexible material 2610 are essentially flat and, thus, maybe positioned within a shoewear to achieve a desired configuration. Thatis, the angle of orientation of the forward and the rear footwear moduleor adjustable platform 2305 may be set as desired and as previouslydiscussed.

FIG. 27A illustrates a second exemplary embodiment of the VRB 2720 inaccordance with the principles of the invention.

In this illustrated embodiment, which is similar to that shown in FIG.23A, includes a threaded section 2760 positioned substantially at amid-point of VRB 2360, rather than at an end. In this configuration, VRB2720 operates in a manner as previously discussed, wherein theorientation of the VRB 2720 determines an amount of resistive force theVRB 2720 possess with regard to a force applied to the VRB 2720.

FIG. 27B illustrates a complete footwear module or adjustable platform2705 in accordance with the second exemplary embodiment of the VRB 2720shown in FIG. 27A. As shown, the angle of orientation of the VRBs 2720is substantially zero as the VRBs 2720 are illustrated in a parallelconfiguration. However, it would be understood that the angle oforientation (a) may be set as previously discussed.

As further illustrated, the VRB 2720 extends through the threaded pocketand exits the open end 2520. Further illustrated is the VRBs 2720 may beadjusted to have different lengths with respect to the anchor 2330. Thedifferent lengths of the VRBs extending from the anchors 2330 inconjunction with the orientation of the orientation of VRB 2720 maydetermine an amount of resistive force the VRB 2720 possess with regardto a force applied to the VRB 2720.

FIG. 28A and FIG. 28B illustrate a configuration for manufacturing ashoewear incorporating a footwear module or adjustable platform 2305 inaccordance with the principles of the invention.

FIG. 28A illustrates a footwear module or adjustable platform 2305including a plurality of entry holes 2820 in VRB 2320 and 2825 in anchormodule 2330. FIG. 28B illustrates the insertion of alignment stakes 2810into corresponding entry holes 2820 and 2825.

FIGS. 29A and 29B illustrate a side view of a molding jig for retainingthe footwear module or adjustable platform 2305 in a desired positionduring a molding process. In this illustrated aspect, the alignmentstakes 2810 are contained within molding base 2910. The footwear moduleor adjustable platform 2305 is positioned on the alignment stakes 2810through the entry holes 2820 and 2825 as previously discussed. In thisillustrated case, alignment stakes 2810 are sized to position thefootwear module or adjustable platform 2305 at a desired angle. In thisillustrated example, the stakes 2810 are selected such that the footwearmodule or adjustable platform 2305 is oriented at an 8 degree angle withregard to the molding base. However, as has been previously discussed,the orientation of the footwear module or adjustable platform 2305 maybe selected to satisfy desired conditions. Although, the footwear module2305 is shown at an eight (8) degree angle, it would be appreciated thatthe footwear module 2305 may be set at any desired angle. Preferably,the footwear module 2305 is set within a range of zero (0) totwenty-five (25) degrees.

FIG. 29B illustrates an additional setup configuration of footwearmodule positioning at a predetermined incline held in place by two setsof positioning pins 2810. One set on pins is secured to the bottom 2910of the mold while the other set of pins 2810 is secured to a top 2920 ofthe mold.

When the mold closes wherein the top 2920 engages the bottom 2910, thefootwear module platform 2305 is held in position, as a polymer isinjected into the sealed mold to form the shoe sole. The bottom and toppin sets the footwear module securely in position in situ of the mold.

Two sets of pins are required when higher injection pressures are usedto ensure module position in situ during molding. Two pin sets provide acompressive sandwich, i.e., top down/bottom up, that creates a strongestclamping force to hold the module in position, when the mold is closedand sealed for polymer injection.

FIG. 30 and FIG. 31 illustrated molding configurations for the shoewearshown in FIG. 23A and FIG. 26A, wherein the alignment stakes arepositioned within the base 2910, the footwear module or adjustableplatforms 2305 are positioned on alignment stakes 2810 to achieve adesired orientation of a corresponding footwear module or adjustableplatform 2305 and the sole is then molded containing the footwear moduleor adjustable platforms 2305 set at the desired orientation.

Note in this case, the rear footwear module or adjustable platform 2305is set at an angle different than that shown in FIG. 23A and FIG. 26A,to illustrate that the orientation of the footwear module or adjustableplatform 2305 may be changed as desired.

In this illustrated example, VRB 3220 is representative of an elongatedVRB having a major axis (X) greater than a minor axis *Y).

Further illustrated is a bulbous section 3230 at the free end of the VRB3220, The bulbous (e.g., spherical) section 3230 further includes anindentation 3260. Indentations 3260 may similar to the indentations 1860(FIG. 18A) or 2530 (FIG. 25C) operate to rotate the VRB 3220 usingadjustment tool, similar to tool 2510.

In the case the indentations 3260 are incorporated into the VRB 3220then the corresponding access entry point (e.g., 2350, FIG. 23B; 1530,FIG. 13C) is positioned such as access to indentation 3260 is achieved.

Somereinforcements include fibers, such as fiberglass, metal, polymericfibers, graphite fibers, carbon fibers, boron fibers and Nano-compositeadditives, e.g. carbon nano-tubes, et al, to fill the molecular gaps,therefore strengthening the material.

Additional materials that the resistance rods or VRB's may also becomposed of include high tensile aircraft aluminum and high carbonspring steel and/or high tensile strength to weight materials.

Although the different applications of the VRBs shown herein refer toVRB 100 (type I), it would be recognized that each of the applicationsmay incorporate one or more of the other type of VRBs (i.e., type IIthrough type VII) without altering the scope of the invention.

The resilient VRB's shown in herein may be used with or in conjunctionwith sports equipment and exercise apparatus to create meaningfulexercise and or other useful mechanisms. For example, devices suitablefor exercise equipment, sports equipment, home improvement and medicalmobility may be created to selectable control bending strength orresistance ranges to impart performance benefits. VRB's may be securedat one or more fixed points with the appropriate device may be used toprovide appropriate variable resistance. In addition, the VRBs may behandheld at various points along the beam length to affect fulcrumresistance and or rotated to different incremental orientations toaffect resistance with discrete geometric cross sections. In one aspectof the invention, VRB's may be perpendicularly mounted to a variety ofmechanical apparatus to affect resistance and may additionally behandheld in the air to expand the exercise envelop.

The VRB's described herein may be manufactured based on a methodselected from a group consisting of: rapid prototyping,stereolithography, molding, casting, extrusion and other known in theart.

A VRB's, which may be solid, semi-hollow or hollow, with or withoutgeometrically created I-beam effect (i.e., spines) on the outside orinterior diameter generates resistance depending on the axis oforientation and/or a fulcrum position has been described herein. VRBs100, with incorporated I-beam geometry on the outside diameter, canallow for the dynamic adjustment of resistance of the device. Anadvantage of a device including a VRBs described herein may be—compact,lightweight and offer the ability to more easily and quickly change adesired level of resistance than is typically found in units usingweights, rubber bands, bows or springs. By simple hand reposition, asshown in FIG. 3, or rotation of beam of the incorporated into the devicea desired resistance level may be achieved. The VRBs 100 disclosed,herein, can provide resistance, depending on the orientation of thebeam, to the user. In addition, the device can vary the resistanceprovided to the user during an exercise, without interrupting theexercise cycle. Additional beam resistance is achieved depending uponthe relative orientation of the beam within a 180° degree hemisphere ofmovement relative to the user. Hence, according to the principles of theinvention, a progressive dynamic resistance may be achieved with avariation of the orientation of the beam or shaft shown herein.

The principle of Progressive Dynamic Resistance (PDR) are:

controlled and rotatable (variable) resistance beam with ergonomic workzones:

Multiple, sequential, mechanical resistances are achieved for thepurpose of rehabilitation and exercising of endo-skeletal musculature.

Increased/decreased incremental mechanical resistance and exerciseadjustability is achieved through beam rotation and or fulcrum handposition relative to the beam or arc length/distance along theresistance beam to impart desired work load.

PDR's 180° or 360° degree range of dynamic arcing motion provides anexercise resistance program for every male or female body type withvariability in muscle size and strength to provide gain after unilateralresistance training of progressive resistance exercise (PRE).

PDR's incremental mechanical resistance capability (i.e., resistanceadjustability through rotation and or fulcrum hand position) facilitatesand customizes the user's strength curve and exercise requirements fromsimply moving hand/leg position to tailor the optimum resistance tomaximize the workout of the targeted muscle group.

PDR resistance beam technology does not have mechanical flat spots ordead spots and provides continuous resistance curve to maximize workoutloading on the targeted muscle groups, thus creating a more effectivework out.

PDR's bend/arc/range of motion means that as the resistance beam is bentfarther away from a plane of minimum resistance, the sustainedmechanical resistance incrementally increases, creating a progressivelymore intense and effective work out/work load on the target musclegroup.

Continuous Progressive Dynamic Resistance loading from the bending ofVRBs 100 is a highly effective bio-mechanical exercise.

In other aspects of the invention, different types of sport equipmentand apparatus may incorporate the VRBs 100 technology described herein.Examples in which VRB 100 technology may be applied are:

FIGS. 3, 4and 5 illustrate an exemplary system in accordance with the principlesof the invention.

FlexBoard product represents an apparatus or structure wherein atransportable structural panel resting on the ground with rod holdersinto which VRB's 100 are inserted perpendicularly to allow users toperform a variety of exercises. FIG. 6 illustrates an exemplaryFlexBoard system in accordance with the principles of the invention.

FlexGym represents an apparatus or structure wherein the VRB 100technology of the present invention may be incorporated into a pluralityof structural tracks with rod holders providing multiple positions intowhich the VRB 100 resilient adjustable or non-adjustable solid ortubular rods and other exercise apparatus are inserted to allow users toperform a variety of exercises in an I-formed structure, with acantilevered bench that folds down or may be a free form bench. Inaddition, the floor tracks, which also comprise the lower structure ofthe unit, can be optionally retracted to the vertical tracks when not inuse.

In one aspect of the invention a means to track and record exercisecycles per set of the user may be incorporated. For example, biometricdata of the user may be recorded on a smart card, a smart phone, acomputer, etc. so exercise cycles can be recorded. In addition,biometric data of the user may be conveyed by magnet, reflector, RFID,WiFi or other means to measure or quantify exercise cycle.

In another aspect of the invention, the exercise apparatus may includesensors (e.g., WiFi) to sense proximity of the user as the userapproaches the exercise apparatus. The sensors may also be incommunication with a user's smart phone transmitter or other technicalmeans and the exercise apparatus respond may be setup to correspond to auser's particular exercise regime.

Another embodiment of the exercise apparatus sensors would recognize auser via sensor or WiFi or iPhone transmitter that would initiateservo-mechanisms to proactively set a customized workout cycle. Thiswould mean that the track holder along the track, be it vertical orhorizontal, and would be matched to the user's ergonomic body size andrequirements.

In another aspect of the invention a video display or monitor may beincorporated to enable a user to receive instructions regarding aparticular exercise or to watch one or more programs of interest duringthe exercise session.

Returning to FIG. 3, FIG. 3 represents a method for incorporating theVRB 100 technology into an apparatus for exercise with one or moreanchor point which is represented by the product FlexToner. Morespecifically, the present invention related to a resilient adjustable ornon-adjustable solid or tubular rod exercise apparatus handheld at oneor more places and flexed.

Other VRB 100 exercise apparatus applications are, but not limited to,upper and or lower body exercise machines: (e.g. treadmills, stairclimbers, elliptical trainers, stationary bikes, mobility, medical,rehabilitative systems that create and control selectable bendingstrength or resistance ranges with fixed rotation to impart PDR)isolating the upper and or lower body for exercise.

The present invention may be incorporated into devices that provide forlow impact/low resistance exercises (e.g., Rehabilitative and Geriatricexercisers) to strengthen and rehabilitate post surgical, bed-ridden,sport injury and or geriatric benefit. Typically, these devices mayemploy VRBs 100 that are matched to the strength of the user. Forexample, VRB 100 may be adjusted to provide rigid support during aninitial healing phase of a sports injury and then adjusted to providelesser amount of support to compensate for progress during the healingof the sport injury.

Although, the present invention is described with regard to a pluralityof different equipment, it would be recognized that the describedequipment are merely examples to which the VRB technology describedherein may be applied. The examples provided herein are merelyillustrative of the application of the claimed technology and theexamples are not intended to limit the subject matter claimed.

In other aspects of the invention, other types of sports equipment andapparatus may incorporate the VRB 100 technology described herein.Examples in which VRB 100 technology may be applied are, but not limitedto:

Golf Clubs

Golf clubs may be formed of graphite, wood, titanium, glass fiber orvarious types of composites or metal alloys. Each varies to some degreewith respect to stiffness and flexibility. However, golfers generallycarry onto the golf course only a predetermined number of golf clubs.

Varying the stiffness or flexibility of the golf club is not possible,unless the golfer brings another set of clubs of a differentconstruction. Even in that case, however, the selection is stillsomewhat limited.

Nevertheless, it is impractical to carry a huge number of golf clubsonto the course, each club having a slight nuance of difference inflexibility and stiffness than another. Golf players prefer taking ontothe course a set of clubs that are suited to the player's specific swingtype, strength and ability.

Returning to FIG. 8, which illustrates an exemplary embodiment of aninternal VRB 100 in a hollow shaft (e.g., a golf shaft). As previouslydiscussed, the VRB 100 is centrally raised or lowered within the golfshaft, the fulcrum or kick point is raised or lowered, thereby changingthe shaft flex. The 360 degree symmetrical geometry provides a solutionfor an adjustable golf club and would be fully compliant with theexisting USGA rules of golf and assorted international golfassociations.

Running Shoes, Training Shoes, Basketball Shoes

The transmission of the shoe wearer's strength (power) from their legsinto the ground is directly affected by the sole stiffness of the shoe.Runners may gain more leverage and, thus more speed, by using a stiffersole. Basketball players may also affect the height of their jumpsthrough the leverage transmitted by the sole of their shoes. If the soleis too stiff, however, the toe-heel flex of the foot is hindered.

It is advantageous that the shoe wearer have the ability to tailor thesole stiffness to his/her individual weight, strength, height, runningstyle, and ground conditions. Preferably, the shoe wearer may tailor thestiffness of the shoe sole to affect the degree of power and leveragethat is to be transmitted from the wearer into the ground.

In this example, VRB 100 are insertable, insert molded or structurallyconnected to the shoe sole in lateral and/or longitudinal positionswithin the sole and are all rotatable to a fixed and mechanically lockedposition to effect custom flexural resistance range. Additionally, zonesof resistance are customizable, e.g. the right pad of the foot can bemade more rigid than the left pad side through the beam's rotatedorientation. Thus, the degree of flexibility may be customized toaccommodate a user's desired preferences.

Incorporation of the VRB 100 technology into running shoes, as shown inFIG. 11, and FIG. 23-34B provides a dynamic adjustable in-solesuspension system that can absorb the weight of the wearer and releaseit per each step.

Hockey Sticks

Hockey includes, but is not limited to, ice hockey, street hockey,roller hockey, field hockey and floor hockey.

Hockey players may require that the flexure of the hockey stick bechanged to better assist in the wrist shot or slap shot needed at thatparticular junction of a game or which the player was better at making.Players may not usually leave the field to switch to a different pieceof equipment during play.

Younger players may require more flex in the hockey stick due to lack ofstrength and such flex may mean the difference between the youngerplayer being able to lift the puck or not when making a shot since astiffer flex in the stick may not allow the player to achieve such lift.

In addition, as the younger players ages and increases in strength, theplayer may desire a stiffer hockey stick, which in accordance withconvention means the hockey player would need to purchase additionalhockey stick shafts with the desired stiffness and flexibilitycharacteristics. Indeed, to cover a full range of nuances of differingstiffness and flexibility characteristics, hockey players would haveavailable many different types of hockey sticks.

Even so, the hockey player may merely want to make a slight adjustmentto the stiffness or flexibility of a given hockey stick to improve thenuances of the play. Thus, the incorporation of the VRB technology intohockey sticks (shaft and/or blade) provides for variations in thestiffness and flexibility that may be adjusted as the user progresses intheir ability.

Incorporation of the VRB technology into hockey sticks is similar tothat shown in FIG. 7.

In other aspects of the invention, different type of Do-it-Yourself(DIY) and Home Improvement products and devices may incorporate the VRBtechnology described herein. Examples in which VRB technology may beapplied are:

Lawn Equipment:

Adjustable lawn rake with VRB 100 tines:

The VRB 100 technology described by the present invention may beincorporated into a lawn rake. In this case, an adjustable rake with arotatable VRB 100 down the shaft of the rake may be created. The VRB 100facilitates the adjustment of the lawn rake, with the ability to adjuststiffness of the shaft relative to the load (e.g., light grassclippings, heavy grass clipping, wet grass clippings).

Incorporation of the VRB 100 technology into lawn rake (or other similarhandled devices) is similar to that shown in FIG. 10A and FIG. 10B.

In another embodiment, the VRB 100 technology described by the presentinvention may be incorporated into tines of a lawn rake creating anadjustable rake. Thus, the VRB 100 facilitates the adjustment of alawn/utility rake by providing the ability to create variable shaftresistance for light or heavy duty gravel raking due to its rotatedorientation. The VRB 100 adjustment setting may simultaneously rotatethe rake's tines from 0° to 90°, thus affecting a stiffer tineorientation. The tines may be elliptical or oval in shape in anembodiment of an elliptical VRB 100. When the tines are in a 0°orientation, they are the most flexible and suitable for raking leavesor light duty yard work. When the tines are in a 90° orientation, theyare the most rigid and suitable for raking heavy duty gravel. Theflexural change of tines can be further impacted by means of adjustingwhere the center point of a fulcrum of the flex of tines is located.

FIG. 10A illustrates an exemplary lawn rake incorporating the VRB 100technology disclosed herein. FIG. 10A and FIG. 10B illustrates a rakeassembly 1000 including a handle 1010 and a tine assembly 1015 includinga plurality of VRB 100 tines that are simultaneously adjusted throughrotation. FIG. 10B illustrates a bottom view of rake 1000 showing theorientation of the tines 100 at a maximum resistance level (90 degreeorientation).

Thus, the incorporation of the VRB 100 technology in the tines creates aflexible lawn rake to alter the flex characteristics of the rake.
